[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0049] A multi-gel electrophoresis tank according to an embodiment of the present application, such as Figure 8-Figure 12As shown, it comprises: a multi-gel position electrophoresis tank body and at least one gel rack assembly 2, the gel rack assembly 2 is arranged in the corresponding electrophoresis position 12, it should be noted that the gel rack assembly 2 comprises a bracket 21, the two sides of the bracket 21 are respectively connected to the corresponding gel plates 24, a preset space is formed between the bracket 21 and the gel plates 24, for filling the buffer solution; the bracket 21 is connected to a positive electrode 22 and a negative electrode 23, for respectively connecting the positive and negative electrodes of the power supply, the positive electrode 22 is connected to a positive electrode conductive member, the other end of the positive electrode conductive member is located at the bottom of the bracket 21, and the other end of the positive electrode conductive member is used to be conductively connected with the buffer solution in the electrophoresis position 12; the negative electrode 23 is connected to a negative electrode conductive member, the other end of the negative electrode conductive member is conductively connected with the buffer solution in the liquid storage cavity formed by the gel rack assembly 2 and the gel plates 24;

[0050] The positive electrode 22 and the negative electrode 23 form an electric field between the buffer solution in the liquid storage chamber formed by the gel rack assembly 2 and the gel plate 24 and the buffer solution in the electrophoresis position 12 through the negative electrode conductive member and the positive electrode conductive member, thereby promoting the movement of charged ions in the buffer solution in the gel to complete the electrophoresis experiment. This is the prior art, such as the working principle of the gel rack assembly disclosed in publication number CN108490059A, which will not be repeated here.

[0051] The multi-gel electrophoresis tank in this embodiment is as follows: Figure 1-Figure 6 As shown, it includes: a tank body 1, the tank body 1 has a cavity, at least two electrophoresis positions 12 for matching with the glue rack assembly 2 are formed in the cavity, a protrusion 13 is provided between two adjacent electrophoresis positions 12, the protrusion 13 is detachably connected to the cavity, or the protrusion 13 and the cavity are integrally formed, so that an independent space is formed between two adjacent electrophoresis positions 12; an observation space is formed between the outside of the protrusion 13 and the tank body 1, and the observation space is hollow, which is convenient for the observation space to intuitively observe the electrophoresis state of the two inner glue plates 24, thereby improving the experimental efficiency; in this embodiment, the protrusion 13 has a first preset height, and the first preset height is not lower than the position of the anode outlet 241 of the glue plate 24 of the glue rack assembly 2; the first preset height is not higher than the top of the glue plate 24 of the glue rack assembly 2. If the height is too high, materials will be wasted.

[0052] Such a design first ensures that the gel plate 24 located in the middle of the gel rack assembly 2 can be observed intuitively. Secondly, a protrusion 13 is added between two adjacent electrophoresis positions 12. When one side is used for electrophoresis, it is only necessary to add buffer solution on the corresponding side, and there is no need to fill both electrophoresis positions 12 with buffer solution, which can greatly save buffer solution. Ice cubes and other cooling materials can also be added to the electrophoresis position 12 on the other side to reduce the temperature of the buffer solution, facilitate heat dissipation, and improve the quality of electrophoresis. It should be noted that, in order to facilitate observation, the multi-gel electrophoresis tank is made of light-colored materials as a whole, such as transparent materials.

[0053] In addition, the top of the raised portion 13 is in a platform shape, which is convenient for placing heat dissipating materials, such as ice cubes.

[0054] In one embodiment, if Figure 5 As shown, a preset angle A is formed between two adjacent electrophoresis positions 12, and the protrusion 13 is located in the area where the preset angle A is located. The preset angle A is 5-90 degrees; preferably, the preset angle A is 5 degrees, 10 degrees, 30 degrees, 40 degrees or 50 degrees, and the glue plate 24 located in the middle of the glue rack assembly 2 can be best visually observed while satisfying the function.

It should be noted that the glue plate 24 and the anode outlet 241 are prior arts, such as the glass slide assembly and the lateral opening groove disclosed in the publication number CN108490059A, the glass slide assembly corresponds to the glue plate 24, and the lateral opening groove corresponds to the anode outlet 241. This design ensures that the positive electrode conductive part of the glue rack assembly 2 is conductive with the buffer solution in the electrophoresis position 12, that is, the buffer solution here must ensure that it can cover the positive electrode conductive part, while reducing the buffer solution in the two adjacent electrophoresis positions 12, it is also convenient for the buffer solution in the two adjacent electrophoresis positions 12 to be filled in time, and this situation is used when the two adjacent electrophoresis positions 12 are both performing electrophoresis; it can also be used as a heat dissipation space to facilitate heat dissipation during electrophoresis.

With this design, the glue rack assembly 2 is limited up, down, left, and right, with a good effect.
