Abstract
Description
Technical Field
[0001] This utility model relates to the field of biochip and diagnostic reagent technology, and in particular to a protein detection device using the imprinting method. Background Technology
[0002] Western blotting is a commonly used experimental method in molecular biology, biochemistry, and immunogenetics. Its basic principle is to stain cell or tissue samples treated with gel electrophoresis with specific antibodies. By analyzing the location and depth of the staining, information about the expression of specific proteins in the analyzed cells or tissues can be obtained.
[0003] Protein blotting requires antibody cultivation of the protein-loaded membrane. For example, Chinese patent CN 207292804 U discloses a protein blotting kit that saves antibody usage. Specifically, during antibody cultivation, the antibody solution is appropriately diluted, and the diluted antibody solution is dropped onto a square carrier plate. A nitrocellulose membrane is taken out from the storage box and placed over the antibody solution, ensuring that the nitrocellulose membrane is evenly distributed to avoid the formation of air bubbles. The nitrocellulose membrane reduces the evaporation of the antibody solution. The evaporation of the antibody solution is further reduced by the snap-fit mechanism of the box lid and body and by temperature regulation, thus saving antibody solution and facilitating the recovery of excess antibody solution.
[0004] The disadvantages of the above-mentioned patent are that air bubbles need to be avoided when covering with nitrocellulose membrane, which requires a high level of experience from the operator and is not suitable for beginners. Secondly, when recovering the antibody solution, the lid of the reagent kit needs to be opened, the nitrocellulose membrane needs to be removed, and then the antibody solution needs to be poured out, which is cumbersome and prone to problems.

Detailed Implementation
[0019] To enhance understanding of this utility model, it will be described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.
[0020] like Figure 1 and Figure 2 The diagram shows the structure of reaction kit 1 in the blotting protein detection device. Reaction kit 1 specifically includes a base plate 11 and a housing 12. The housing 12 can be fastened to the base plate 11, and a sealing ring can be placed at the fastening point to prevent leakage.
[0021] The upper surface of the box 12 is provided with a sample dispensing hole 121 and an observation hole 122. The interior is provided with a sample dispensing channel 123, an observation channel 124 and a recovery chamber 125. The sample dispensing hole 121 is connected to the sample dispensing channel 123, the observation hole 122 is connected to the observation channel 124, and the recovery chamber 125 has only one end open.
[0022] Corresponding to the housing 12, a sample application area 111, a reaction area 112, and a recovery area 113 are sequentially arranged on the upper surface of the base plate 11. The bottom shapes of the sample application channel 123, the observation channel 124, and the recovery chamber 125 are adapted to the edge shapes of the sample application area 111, the reaction area 112, and the recovery area 113, respectively. After the housing 12 and the base plate 11 are fastened together, the sample application area 111 and the sample application channel 123 are connected, the reaction area 112 and the observation channel 124 are connected, and the recovery area 113 and the recovery chamber 125 are connected, forming their respective relatively independent areas. However, liquid can flow between these areas through liquid flow channels.
[0023] According to a preferred embodiment of the present invention, such as Figure 2As shown, the connection between reaction zone 112 and sample loading zone 111 is designed as a ramp to facilitate liquid flow into reaction zone 111. An outlet is provided at the connection between reaction zone 112 and recovery zone 113 to facilitate liquid flow out into recovery zone 113. The liquid flow method can be varied and is not limited here.
[0024] According to another preferred embodiment of the present invention, two slots are provided opposite to the portions of the reaction zone 112 that are higher than the sample loading zone 111 and the recovery zone 113, and the NC membrane can be inserted into the slots for fixation.
[0025] A pipe 14 is provided on the side wall of the box 12. One end of the pipe 14 is connected to the bottom of the recovery chamber 125, and the other end is connected to the waste liquid pipe 15. The other end of the waste liquid pipe 15 is connected to the outside.
[0026] To facilitate the flow of waste liquid from the recycling area 113 into the pipe 14, a protrusion 114 that serves as a guide can be provided at the point where the recycling area 113 contacts the pipe 14. The protrusion 114 extends into the bottom of the pipe 14, and the bottom opening of the pipe 14 is slightly higher than the protrusion 114 to facilitate the flow of waste liquid.
[0027] like Figure 3 The waste liquid recovery device 2 shown includes a circular support 21, the interior of which is a hollow cavity. A circular turntable 22 is positioned at the center of the support 21, and the support 21 and the turntable 22 are connected by several connecting bridges 23. The support 21 has several connecting holes 211, the positions of which correspond to the positions of the connecting bridges 23, i.e., one connecting bridge 23 corresponds to one connecting hole 211. The turntable 22 has several through holes 221 for connecting to the motor shaft.
[0028] In use, the reaction kit 1 is fixed on the connecting bridge 23, and the waste liquid tube 15 on the reaction kit 1 is inserted into the connecting hole 211. When the motor is turned on, the waste liquid collection device will be rotated through the turntable 22. The rotation speed is controlled to rotate at a low speed first to facilitate the reaction in the reaction zone. When the reaction is completed, the motor rotates at a high speed, so that the waste liquid in the reaction kit is thrown into the cavity of the support 21 through the waste liquid tube, thus completing the automatic collection of waste liquid.
[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
