Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to an ECL reagent configuration reaction device. Background Art

[0002] ECL reagent, namely chemiluminescent horseradish peroxidase substrate, is currently the most sensitive reagent in Western blotting detection. In practice, the configuration of ECL reagent includes the following steps: 1. Perform conventional SDS-PAGE, transfer and Western Blot steps. During the process: label IgG with HRP or use the primary antibody-streptavidin-biotin-HRP clamp method. 2. Take equal volumes of reaction solution A and reaction solution B respectively, put them into a clean container and mix them, and react to generate ECL working solution; 3. After the last wash of Western Blot, take out the reaction membrane with tweezers, absorb the excess washing solution with filter paper and place it in a plastic container. 4. Transfer the ECL working solution in the clean container to the reaction membrane placed in the plastic container through a pipette, and place it for 1-3 minutes to allow the secondary antibody on the reaction membrane to develop color. The problem with the above scheme is that during the reaction process of steps 2 and 4, external sunlight exposure will cause the properties of the ECL working solution to change. In addition, the process of transferring the ECL working solution into the plastic container using a pipette is prone to cause the loss of the ECL working solution. Therefore, how to develop a new ECL reagent configuration reaction device to overcome the above-mentioned problems in the prior art is a direction that technical personnel in this field need to further study.

[0029] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0030] Example 1, please refer to Figure 1-4 :

[0031] An ECL reagent configuration reaction device, comprising:

[0032] The reaction box 100 has an opening at the top and is provided with a corresponding box cover 300 . Both the reaction box 100 and the box cover 300 are made of light-shielding materials.

[0033] The reaction box 100 is provided with a first reaction area 110 and a second reaction area 120. The first reaction area 110 is used to place a reaction membrane 111. The second reaction area 120 is used to realize the reaction process of forming an ECL working solution from a reaction liquid A and a reaction liquid B. A flow channel is provided between the second reaction area 120 and the first reaction area 110, and the flow channel is conductively connected; a switch component 200 is provided on the flow channel, and the switch component 200 is configured to cut off / conduct the flow channel.

[0034] Specifically, in this example: the reaction box 100 is a rectangular box body, and the reaction box 100 includes a bottom wall and four side walls.

[0035] The second reaction area 120 is a cylindrical cavity disposed in the reaction box 100. The cylindrical cavity is a rectangular hollow column with an open top. The cylindrical cavity is surrounded by the bottom wall, any two of the four side walls connected to each other, and the first baffle 121 and the second baffle 122 connected vertically to each other. That is, one end of the plate body of the first baffle 121 is vertically connected to one side wall, the other end of the plate body of the first baffle 121 is vertically connected to one end of the plate body of the second baffle 122, and the other end of the plate body of the second baffle 122 is vertically connected to another side wall.

[0036] The plate body of the first baffle 121 is provided with a U-shaped notch, the U-shaped notch includes an arc-shaped bottom edge constituting the flow channel, and a slot 140 extending in the vertical direction is respectively provided on both sides of the U-shaped notch. The switch assembly 200 includes a switch baffle 210, the shape of which is configured to match the U-shaped notch, and the two sides of the switch baffle 210 are respectively connected with a clamping strip, and the shape of the clamping strip is configured to match the clamping slot 140. That is, the two clamping strips can be inserted into the two clamping slots 140 synchronously and slide up and down in the vertical direction. The top of the switch baffle 210 is also provided with a convex edge 211 for holding. The switch baffle 210 is configured such that when the two clamping strips slide synchronously along the two clamping slots 140 until the lower end surface of the convex edge 211 abuts against the upper end surface of the first baffle 121, the switch baffle 210 blocks the left and right sides of the U-shaped notch.

[0037] The first reaction area 110 is a space in the box body located outside the cylindrical cavity, and the reaction membrane 111 is laid on the bottom of the first reaction area 110 .

[0038] In practice, the working process is as follows: when preparing the ECL reagent, first open the box cover 300, pour the A reaction solution (luminol) and the B reaction solution (hydrogen peroxide) into the second reaction area 120 (i.e., the columnar cavity) through the top opening of the reaction box 100, and cover the box cover 300 to allow the A reaction solution and the B reaction solution to react in a lightless environment to form the ECL working solution. Subsequently, open the box cover 300, and pull the switch baffle 210 upward from the U-shaped notch, so that the two sides of the U-shaped notch lose the shielding of the switch baffle 210 and are connected, and the ECL working solution flows out of the columnar cavity through the U-shaped notch and contacts the reaction membrane 111, and cover the box cover 300 to allow the secondary antibody on the reaction membrane 111 to develop color. In this way, the influence of external sunlight on the properties of the ECL working solution is reduced, and the loss of the ECL working solution during transfer is reduced.

[0039] Example 2, please refer to Figure 5 :

[0040] The difference between Example 2 and Example 1 is that in this example:

[0041] The columnar cavity is surrounded by the bottom wall, any one of the four side walls, and a first baffle 121 , a second baffle 122 , and a third baffle 123 that are vertically connected in sequence; the U-shaped notch is located on the first baffle 121 .

[0042] Example 3, please refer to Figure 6 :

[0043] The difference between this example and Example 1 is that in this example:

[0044] A partition plate 130 is provided in the reaction box 100, and the partition plate 130 is configured to divide the inside of the reaction box 100 into two reaction zones, each of which includes the first reaction area and the second reaction area. Compared with Example 1, the staff can configure different ECL reagents in the two reaction zones, thereby improving work efficiency.
