Description

Technical Field

[0001] This invention relates to the field of polyacrylamide gel electrophoresis and protein immunoblotting in molecular biology experiments, and in particular to a foldable gel cutting device. Background Technology

[0002] Western blotting is a routine protein detection technique for identifying a specific antigen. It utilizes SDS-polyacrylamide gel electrophoresis to separate proteins from a complex mixture based on their molecular weight. The proteins are then transferred to a solid support (such as a nitrocellulose membrane or PVDF membrane), and a specific antibody is used to detect the target protein. Qualitative and semi-quantitative analysis of the target protein is achieved through the specificity of antigen-antibody binding. In this experiment, the SDS-polyacrylamide gel and the nitrocellulose or PVDF membrane should be of the same size, and the amount of antibody used is determined based on the membrane size. Since membranes and antibodies are relatively expensive materials in this experiment, it is necessary to conserve their use; therefore, the smallest possible membrane size and the minimum amount of antibody should be used.

[0003] Current technology involves researchers using a blade to cut the gel to the required size, which is time-consuming and results in uneven cut edges. Sometimes, to save time, researchers skip cutting the gel and directly transfer a membrane of the same size as the gel, leading to significant waste of materials and increased costs. Under current conditions, researchers have a clear need to simultaneously save experimental time and materials, thereby reducing costs. Therefore, it is necessary to design a device that can quickly and accurately cut the gel.

[0004] To address this, we propose a foldable rubber cutting device. Utility Model Content

[0028] Example 1

[0029] like Figure 1-3 As shown, this utility model provides a foldable rubber cutting device, including a main ruler 1, a folding rod 6 fixedly connected to one end of the main ruler 1, a folding shaft 9 connected to one end of the folding rod 6, a stop plate 8 fixedly connected to one end of the folding shaft 9, a scale value set on the surface of the main ruler 1, and two sets of rubber cutting components slidably sleeved on the surface of the main ruler 1.

[0030] Specifically, the baffle plate 8 is a cube, and its length is greater than that of the main ruler 1 and the sliding groove 11, preventing the glue-cutting component from falling off. With the cooperation of the folding rod 6 and the folding shaft 9, it can be folded 180° to either the front or back of the main ruler 1, making it easy to store the entire device in a storage box. The thickness of the folding rod 6 is the same as the thickness of the main ruler 1 and less than that of the sliding groove 11. The glue-cutting component allows for glue-cutting operations. The main ruler 1 is made of stainless steel.

[0031] In this embodiment, the cutting assembly includes a cutting blade 2. A blade 3 is fixedly connected to one side of the cutting blade 2. A sliding groove 11 is formed on the surface of the cutting blade 2. The sliding groove 11 is slidably connected to the surface of the main ruler 1. A moving groove 10 is formed on one side of the sliding groove 11. Limiting grooves 12 are formed on both the upper and lower sides of the moving groove 10. A limiting block 4 is slidably connected to the inner wall of the sliding groove 11. A locking block 5 is fixedly connected to one side of the limiting block 4 and is slidably connected to the inner wall of the moving groove 10. Limiting sliders 13 are fixedly connected to the upper and lower sides of the locking block 5 and are slidably connected to the inner walls of the corresponding limiting grooves 12. Two springs 7 are fixedly connected to one side of the locking block 5. One end of the spring 7 is fixedly connected to one side of the inner side of the moving groove 10.

[0032] Specifically, the spring 7 presses the limiting block 4 against the main ruler 1, thus limiting the installation and use of the rubber cutter 2 on the surface of the main ruler 1. The locking block 5 can slide to a limited position under the action of the limiting groove 12 and the limiting slider 13. The rubber cutting operation can be performed by the action of the blade 3. The rubber cutter 2 is made of stainless steel.

[0033] The specific working principle and usage method of this utility model are as follows:

[0034] This utility model provides a foldable rubber cutting device, such as... Figure 1-3 As shown, when using the device, remove it from the storage box. At this time, the main ruler 1 and the cut film 2 are stacked parallel to each other, and the folding rod 6 is closed through the folding shaft 9. Hold the stop plate 8 with one hand and the main ruler 1 with the other, and forcefully pry the stop plate 8 and the main ruler 1 outwards. The folding rod 6 opens, making the stop plate 8 and the main ruler 1 a straight line, perpendicular to the cut film 2. Then, rotate the stop plate 8 and the main ruler 1 counterclockwise by 90°, so that the front of the main ruler 1 is parallel to the sliding groove 11. Hold the main ruler 1 with one hand and pinch the locking block 5 on the cut film 2 with the other hand and slide it on the inner wall of the moving groove 10, compressing the spring 7. At this time, the limiting pressure block 4 retracts, the width of the sliding groove 11 increases, and the cut film 2 is dragged through the sliding groove 11 and through the main ruler 1. Release the locking block 5 at the required scale or length, so that the limiting pressure block 4 extends and presses down on the main ruler 1 under the restoring force of the spring 7, fixing the position of the cut film 2. The other cut film 2 can be installed in the same way through the above steps. To begin, place the prepared device over the area of ​​glue to be cut and press down to obtain the desired size of glue. After cutting, clean the device and fold it back into the storage box using the same method. This device can also be used for other experimental cutting applications. This method is simple, convenient, easy to operate, produces aesthetically pleasing cuts of glue, and saves on experimental costs.
