Description

Technical Field

[0001] This utility model relates to the technical field of electrophoresis equipment, and more specifically, to an electrophoresis gel generator. Background Technology

[0002] Western blotting (WB) is a fundamental experiment for detecting protein expression. Invented by George Stark of Stanford University, it was first termed Western Blot by Neal Burnette in his 1981 publication. This experiment uses polyacrylamide gel electrophoresis to separate protein samples. The analyte is protein, the "probe" is an antibody, and the "color development" is achieved using labeled secondary antibodies. High-quality gels are essential for obtaining clear bands. Before transferring proteins to a membrane for WB, they need to be separated by running a gel in a vertical electrophoresis tank. To further reduce experimental costs, researchers often use the gel generator provided with the electrophoresis tank to prepare the gels themselves and run the electrophoresis.

[0003] However, in current glue-making machines, when the glue-making frame with the fixed glass plate is installed on the base plate, the frame is prone to loosening, leading to leakage and affecting the glue-making effect. To prevent the frame from loosening, interference fits and other methods are used to increase the connection strength between the frame and the base plate. However, this makes it difficult to remove the frame from the base plate after glue-making is complete. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where, when a glue-forming frame with a fixed glass plate is installed on a base plate, the glue-forming frame is prone to loosening on the base plate, and even after increasing the connection strength between the glue-forming frame and the base plate, it is difficult to remove the glue-forming frame from the base plate. This invention provides an electrophoretic glue-forming device in which the glue-forming frame will not loosen when fixed on the base plate, and it can also be easily and conveniently removed from the base plate.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An electrophoresis gel casting apparatus is provided, comprising a base, a concave glass plate, a flat glass plate, and a gel casting frame for bonding and fixing the concave and flat glass plates together. The concave and flat glass plates are bonded together to form a receiving cavity. The base is provided with a sealing portion for sealing the bottom of the receiving cavity. First magnetic elements are provided at both ends of the sealing portion, and the first magnetic elements are fixedly installed on the base. Two second magnetic elements are installed on the gel casting frame, and the two second magnetic elements can attract each other with the two first magnetic elements respectively. The second magnetic elements on both sides of the gel casting frame attract and bond with the first magnetic elements at both ends of the sealing portion, respectively. When the first and second magnetic elements are bonded, the top surface of the first magnetic element contacts the bottom surface of the second magnetic element. Both the first and second magnetic elements can be strong magnets, which can further increase the magnetic attraction when they attract each other. Alternatively, one of the first or second magnetic elements can be a strong magnet, and the other can be a metal material that can be attracted by a strong magnet. The sealing portion is a sealing rubber strip or a sealing silicone strip.

[0007] In use, the electrophoresis gel casting device of this invention firstly attaches and fixes a concave glass plate and a flat glass plate to the gel casting frame, forming a receiving cavity. Then, the gel casting frame is fixed to the base. A second magnetic component tightly adheres to the first magnetic component, securing the gel casting frame to the base. When the gel casting frame is fixed to the base, the bottom surfaces of the concave and flat glass plates are tightly fitted with the sealing part on the base, meaning the bottom of the receiving cavity is tightly fitted with the sealing part, sealing the bottom of the receiving cavity and preventing liquid leakage after injection. After the bottom of the receiving cavity is sealed, liquid is injected into the receiving cavity for gel casting. When the gel casting device needs to be removed after gel casting is complete, the magnetic attraction between the first and second magnetic components is released, allowing the gel casting frame to be removed from the base.

[0008] The electrophoresis gel casting device of this utility model uses magnetic attraction to fix the gel casting frame on the base. After the first magnetic component and the second magnetic component attract each other, it can prevent the gel casting frame from becoming loose on the base and causing leakage. At the same time, it can also easily and conveniently remove the gel casting frame from the base.

[0009] Furthermore, both sides of the first magnetic component are provided with positioning protrusions for mounting on the base, and a positioning groove is formed between the two positioning protrusions. The first magnetic component is located on the bottom surface of the positioning groove, and both sides of the glue-making frame can be respectively inserted into the two positioning grooves. Both side walls of the positioning groove are inclined side walls, and the distance from the top of the inclined side wall to the center of the positioning groove is greater than the distance from the bottom of the inclined side wall to the center of the positioning groove. The axial direction of the positioning groove is parallel to the length direction of the sealing part. The positioning groove makes it easier to align the second magnetic component at the bottom of the glue-making frame with the first magnetic component on the base. The inclined side walls of the positioning groove not only serve as guides, facilitating the insertion of both ends of the glue-making frame into the positioning groove, but also facilitate tilting the glue-making frame when separating it from the base, so that one end face of the glue-making frame fits against one side wall of the positioning groove. At this time, the second magnetic component on the bottom surface of the glue-making frame separates from the first magnetic component in the positioning groove, making it easier to remove the glue-making frame from the base.

[0010] Furthermore, each of the opposite sides of the glue-making frame is provided with a positioning part that can be inserted into the positioning groove. Two second magnetic components are respectively installed on the two positioning parts. Each positioning part also has a clamping groove for holding the concave glass plate and the flat glass plate. The positioning part is located on the side wall of the glue-making frame near the bottom of the frame, and its bottom surface is flush with the bottom surface of the frame. The second magnetic components are fixedly installed on the positioning part. By inserting the positioning part into the positioning groove, the volume of the glue-making frame can be further reduced, making it easier to handle and more convenient to fix the flat and concave glass plates on the frame. The clamping groove further constrains the position of the flat and concave glass plates on the glue-making frame.

[0011] Furthermore, the top surface of the sealing part protrudes beyond the top surface of the base; when the concave glass plate and the flat glass plate are fixed to the glue-making frame, the bottom surfaces of the concave glass plate and the flat glass plate are flush with the bottom surface of the glue-making frame. Since the top surface of the sealing part protrudes beyond the top surface of the base, when the glue-making frame is fixed to the base by the first magnetic component, the bottom surfaces of the concave glass plate and the flat glass plate can be tightly pressed against the sealing part, thereby completing the sealing of the accommodating cavity and further improving the sealing performance of the accommodating cavity when the glue-making frame is installed on the base.

[0012] Furthermore, both sides of the sealing portion are provided with baffles to prevent the glue-making frame from shifting, and the baffles are fixedly installed on the top surface of the base. The baffles can prevent the glue-making frame from shifting left and right on the base when it is attracted to the first magnetic component. Specifically, four baffles are provided, and the four baffles are symmetrical about the horizontal axis and vertical axis of the sealing portion on the base.

[0013] Furthermore, there are multiple sealing parts, which are linearly arranged on the base along a direction perpendicular to the axis of the positioning groove. Each sealing part has a first magnetic element at both ends, and each first magnetic element has a positioning protrusion on both sides. There is one positioning protrusion between every two first magnetic elements, meaning the first magnetic elements and positioning protrusions are staggered. Due to the positioning groove and magnetic elements in this application, the glue-making frame can achieve the purpose of enhanced connection strength with the base and easy disassembly with a smaller volume. Therefore, multiple sets of fixing modules composed of sealing parts, first magnetic elements, and positioning grooves can be set on the base (each fixing module can hold one glue-making frame), allowing the base to simultaneously hold more sets of glue-making frames, achieving high-throughput glue making and further improving glue-making efficiency. The preferred number of fixing modules on the base is ten.

[0014] Furthermore, the system also includes clamping clips for holding the concave glass plate and the flat glass plate. There are two clamping clips, each mounted on one side of the adhesive forming frame, and the clamping clips are detachably connected to the adhesive forming frame. The adhesive forming frame uses the clamping clips to hold the flat glass plate and the concave glass plate, further ensuring a tight fit between them.

[0015] Furthermore, the clamping end of the clamping clamp is U-shaped, and the side of the glue-making frame is provided with an installation groove. The two side walls of the installation groove are the first side wall and the second side wall, respectively. The two side walls of the clamping end are the third side wall and the fourth side wall, respectively. The second side wall is provided with a guide groove, and the third side wall is provided with a guide protrusion. When the clamping end of the clamping clamp clamps and fixes the concave glass plate, the flat glass plate, and the first side wall, the guide protrusion extends into the guide groove. When clamping, the clamping clamp clamps the edges of the concave glass plate, the edges of the flat glass plate, and the first side wall of the installation groove within the clamping end cavity of the clamping clamp. At this time, not only can the flat glass plate and the concave glass plate be tightly fitted by the clamping clamp, but they can also be fixed to the glue-making frame. When the third side wall of the clamping clamp extends into the inner cavity of the installation groove, the guide protrusion on the third side wall of the clamping clamp can extend into the guide groove on the second side wall. The setting of the guide protrusion and the guide groove makes it easier to fix the clamping clamp to the glue-making frame. The clamping clip has two guide protrusions on its third sidewall and two guide grooves on its second sidewall. The two guide protrusions can be inserted into the two guide grooves respectively. The two guide protrusions further prevent the clamping clip from rotating on the adhesive holder. The cross-section of the clamping clip's fourth sidewall can be a gradually changing arc, which makes it easier for the clamping clip to withstand slight deformation due to interference fit when holding a flat glass plate, a concave glass plate, and the first sidewall without breaking.

[0016] Furthermore, the third sidewall is also provided with a clamping protrusion located in the inner cavity of the clamping end; the first sidewall is also provided with a lifting portion. When the guide protrusion slides downward along the guide groove to the bottom of the guide groove, the clamping protrusion can slide onto the lifting portion. When the clamping protrusion slides onto the lifting portion, the distance between the third sidewall and the fourth sidewall increases after the third sidewall is deformed by force, further increasing the clamping force of the third and fourth sidewalls on the flat glass plate, the concave glass plate, and the first sidewall, so that the flat glass plate and the concave glass plate can fit tightly together. The part of the lifting portion for the clamping protrusion to slide can be an inclined plane. The top of the inclined plane is flush with the first sidewall, and the bottom protrudes from the first sidewall, so that the guide protrusion gradually clamps the flat glass plate and the concave glass plate as it slides downward in the guide groove, that is, the third sidewall gradually tilts. Meanwhile, in order to make it easier for the clamping protrusion to slide on the lifting part, the clamping protrusion can be set as a hemispherical shape, and the lifting part is provided with a groove for the hemispherical clamping protrusion to slide.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The electrophoresis gel casting device of this utility model uses magnetic attraction to fix the gel casting frame on the base. After the first magnetic component and the second magnetic component attract each other, it can prevent the gel casting frame from becoming loose on the base and causing leakage. At the same time, it can also easily and conveniently remove the gel casting frame from the base.

[0019] The electrophoresis gel casting device of this invention can further clamp the flat glass plate and the concave glass plate by setting a clamping clamp on the gel casting frame, so as to avoid liquid leakage from the side wall of the receiving cavity. Attached Figure Description

[0031] Example 1

[0032] This embodiment is a first embodiment of an electrophoretic gel casting device, such as... Figure 1 and Figure 2As shown, the device includes a base 1, a concave glass plate 2, a flat glass plate 3, and a glue-making frame 4 for attaching and fixing the concave glass plate 2 and the flat glass plate 3. The concave glass plate 2 and the flat glass plate 3 are attached to form a receiving cavity 5. The base 1 is provided with a sealing part 6 that can seal the bottom of the receiving cavity 5. Each end of the sealing part 6 is provided with a first magnetic element 7, which is fixedly installed on the base 1. Two second magnetic elements 8 are installed on the glue-making frame 4, located on opposite sides of the frame 4. The two first magnetic elements 7 can attract and adhere to the two second magnetic elements 8 respectively. When the first magnetic elements 7 and the second magnetic elements 8 are adhered, the top surface of the first magnetic element 7 contacts the bottom surface of the second magnetic element 8. Both the first magnetic elements 7 and the second magnetic elements 8 are strong magnets. The sealing part 6 is a sealing rubber strip or a sealing silicone strip.

[0033] The working principle or process of this embodiment is as follows:

[0034] In this embodiment, the electrophoresis gel casting device is first used by attaching and fixing the concave glass plate 2 and the flat glass plate 3 onto the gel casting frame 4, forming a receiving cavity 5. Then, the gel casting frame 4 is fixed to the base 1. The second magnetic component 8 is tightly attracted to the first magnetic component 7, completing the fixation of the gel casting frame 4 to the base 1. When the gel casting frame 4 is fixed to the base 1, the bottom surfaces of the concave glass plate 2 and the flat glass plate 3 are tightly fitted with the sealing part 6 on the base 1, meaning the bottom of the receiving cavity 5 is tightly fitted with the sealing part 6. The sealing part 6 seals the bottom of the receiving cavity 5, preventing liquid leakage after injection. After the bottom of the receiving cavity 5 is sealed, liquid is injected into the receiving cavity 5 for gel casting. When the gel casting is complete and the gel casting device needs to be removed, the magnetic attraction between the first magnetic component 7 and the second magnetic component 8 is released, and the gel casting frame 4 can be removed from the base 1.

[0035] The beneficial effects of this embodiment are as follows:

[0036] In this embodiment, the electrophoresis gel casting device uses magnetic attraction to fix the gel casting frame 4 to the base 1. After the first magnetic component 7 and the second magnetic component 8 attract each other, it can prevent the gel casting frame 4 from becoming loose on the base 1 and causing leakage. At the same time, it can also easily and conveniently remove the gel casting frame 4 from the base 1.

[0037] Example 2

[0038] This embodiment is a second embodiment of an electrophoretic gel casting device. Based on the first embodiment, this embodiment further defines the fixing and sealing of the concave glass plate 2, the flat glass plate 3, and the gel casting frame 4 on the base 1.

[0039] Specifically, such as Figure 2As shown, the first magnetic component 7 has positioning protrusions 9 on both sides, which are mounted on the base 1. A positioning groove 10 is formed between the two positioning protrusions 9. The first magnetic component 7 is located on the bottom surface of the positioning groove 10. The two sides of the adhesive frame 4 can be inserted into the two positioning grooves 10 respectively. Both side walls of the positioning groove 10 are inclined side walls 11. The distance from the top of the inclined side wall 11 to the center of the positioning groove 10 is greater than the distance from the bottom of the inclined side wall 11 to the center of the positioning groove 10. The axial direction of the positioning groove 10 is parallel to the length direction of the sealing part 6.

[0040] Specifically, there are multiple sealing parts 6, which are arranged linearly on the base 1 in a direction perpendicular to the axis of the positioning groove 10. Each sealing part 6 has a first magnetic element 7 at both ends, and each first magnetic element 7 has a positioning protrusion 9 on both sides.

[0041] Specifically, the top surface of the sealing part 6 protrudes from the top surface of the base 1, and the first magnetic element 7 is embedded in the base 1, that is, the top surface of the first magnetic element 7 is flush with the top surface of the base 1; when the concave glass plate 2 and the flat glass plate 3 are fixed to the glue-making frame 4, the bottom surface of the concave glass plate 2 and the flat glass plate 3 is flush with the bottom surface of the glue-making frame 4.

[0042] Specifically, both sides of the sealing part 6 are provided with baffles 12 to prevent the glue-making frame 4 from shifting. The baffles 12 are fixedly installed on the top surface of the base 1. Four baffles 12 are provided, and the four baffles 12 are symmetrical about the horizontal axis and the vertical axis of the sealing part 6 on the base 1.

[0043] Specifically, such as Figure 3 and Figure 4 As shown, the glue-making frame 4 has positioning parts 13 on both sides that can be inserted into the positioning groove 10. Two second magnetic parts 8 are respectively installed on the two positioning parts 13. The positioning parts 13 are also provided with clamping grooves 1301 that can clamp the concave glass plate and the flat glass plate 3.

[0044] The beneficial effects of this embodiment are as follows:

[0045] The positioning groove 10 facilitates the alignment of the second magnetic element 8 at the bottom of the glue-making frame 4 with the first magnetic element 7 on the base 1. The sidewall of the positioning groove 10 is an inclined sidewall 11. The inclined sidewall 11 not only serves as a guide, facilitating the insertion of both ends of the glue-making frame 4 into the positioning groove 10, but also allows the glue-making frame 4 to be tilted when separated from the base 1, so that one end face of the glue-making frame 4 fits against one sidewall of the positioning groove 10. At this time, the second magnetic element 8 on the bottom surface of the glue-making frame 4 separates from the first magnetic element 7 in the positioning groove 10, making it easier to remove the glue-making frame 4 from the base 1. Due to the positioning groove 10 and magnetic element configuration in this application, the glue-making frame 4 can achieve a stronger connection with the base 1 and easier disassembly with a smaller volume. Therefore, multiple sets of fixing modules consisting of the sealing part 6, the first magnetic element 7, and the positioning groove 10 can be installed on the base 1, allowing the base 1 to simultaneously accommodate more sets of glue-making frames 4, achieving high-throughput glue production and further improving glue production efficiency.

[0046] The top surface of the sealing part 6 protrudes from the top surface of the base 1. When the glue-making frame 4 is fixed to the base 1 by the first magnetic element 7, the bottom surfaces of the concave glass plate 2 and the flat glass plate 3 can be tightly pressed against the sealing part 6, further improving the sealing performance of the receiving cavity 5 when the glue-making frame 4 is installed on the base 1. The baffle 12 can prevent the glue-making frame 4 from shifting left or right. The glue-making frame 4 is inserted into the positioning groove 10 through the positioning part 13, which can further reduce the volume of the glue-making frame 4, making it easier to pick up and easier to fix the flat glass plate 3 and the concave glass plate 2 on the glue-making frame 4.

[0047] Example 3

[0048] This embodiment is a third embodiment of an electrophoretic gel casting device. This embodiment is based on Embodiments 1 and 2, such as... Figures 3-8 As shown, the manner in which the glue-making frame 4 clamps and holds the flat glass plate 3 and the concave glass plate 2 is further defined.

[0049] Specifically, it also includes clamping clips 14 for holding concave glass plate 2 and flat glass plate 3. There are two clamping clips 14, which are respectively installed on both sides of the glue-making frame 4. The clamping clips are detachably connected to the glue-making frame 4.

[0050] Specifically, the clamping end of the clamping clip 14 is U-shaped, and the side of the adhesive frame 4 is provided with an installation groove. The two side walls of the installation groove are the first side wall 15 and the second side wall 16, respectively. The two side walls of the clamping end are the third side wall 17 and the fourth side wall 18, respectively. The second side wall 16 is provided with a guide groove 19, and the third side wall 17 is provided with a guide protrusion 20. When the clamping end of the clamping clip 14 clamps and fixes the concave glass plate 2, the flat glass plate 3, and the first side wall 15, the guide protrusion 20 extends into the guide groove 19. The third side wall 17 of the clamping clip 14 is provided with two guide protrusions 20, and the second side wall 16 of the installation groove is provided with two guide grooves 19. The two guide protrusions 20 can be inserted into the two guide grooves 19 respectively. The cross-section of the fourth side wall 18 of the clamping clip 14 is provided with an arc-shaped gradient protrusion.

[0051] Specifically, the third sidewall 17 is also provided with a clamping protrusion 21, which is located in the inner cavity of the clamping end; the first sidewall 15 is also provided with a lifting portion 22. When the guide protrusion 20 slides down along the guide groove 19 to the bottom of the guide groove 19, the clamping protrusion 21 can slide onto the lifting portion 22. The part of the lifting portion 22 for the clamping protrusion 21 to slide can be an inclined plane. The top of the inclined plane is flush with the first sidewall 15, and the bottom protrudes from the first sidewall 15, so that the guide protrusion 20 can gradually clamp the flat glass plate 3 and the concave glass plate 2 as it slides down in the guide groove 19, that is, the third sidewall 17 gradually tilts. The clamping protrusion 21 is hemispherical, and the lifting portion 22 is provided with a sliding groove for the hemispherical clamping protrusion 21 to slide.

[0052] The beneficial effects of this embodiment are as follows:

[0053] When the third sidewall 17 of the clamping clip 14 extends into the inner cavity of the mounting groove, the guide protrusion 20 on the third sidewall 17 of the clamping clip 14 can extend into the guide groove 19 on the second sidewall 16. The arrangement of the guide protrusion 20 and the guide groove 19 makes it easier to fix the clamping clip 14 on the glue-making frame 4. The two guide protrusions 20 can further prevent the clamping clip 14 from rotating on the glue-making frame 4. The cross-section of the fourth sidewall 18 of the clamping clip 14 has an arc-shaped gradient protrusion, which makes it easier for the clamping clip 14 to clamp the flat glass plate 3, the concave glass plate 2 and the first sidewall 15 without breaking due to slight deformation caused by interference fit. When the clamping protrusion 21 slides onto the lifting part 22, the distance between the third side wall 17 and the fourth side wall 18 increases after the third side wall 17 deforms under force, further increasing the clamping force of the third side wall 17 and the fourth side wall 18 on the flat glass plate 3, the concave glass plate 2 and the first side wall 15, so that the flat glass plate 3 and the concave glass plate 2 can fit tightly together.

For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
