Embodiment 1

[0064] The present embodiment provides a kind of production technique of high-binding force microtiter plate, comprises the following steps:

[0065] S1: The polystyrene beads and steam are continuously mixed in a pre-foaming machine under the stirring of the stirring tank to complete the foaming reaction. The pre-expanding machine is kept open at atmospheric pressure, and the polystyrene beads that have been expanded are overflowed from the top of the pre-expanding machine. After the polystyrene beads are foamed, aging treatment is carried out so that air is mixed into the cells to obtain aged pre-expanded beads. Put the cured pre-expanded beads into the molding equipment for molding treatment to obtain a 12×8 96-well microplate.

[0066] S2: Place the microplate prepared in step S1 in the plasma surface treatment equipment, open the reaction gas inlet valve 2 and the exhaust valve 5, and pass compressed air into the plasma surface treatment equipment, and the compressed air...

Abstract

The invention relates to a production process of a high-binding-force elisa plate. The process comprises the following steps: S1, foaming, curing and forming expandable polystyrene to prepare a foamed polystyrene elisa plate. S2, placing the elisa plate in plasma surface treatment equipment, introducing first gas, and cleaning the surface of the elisa plate. and S3, supplementing second gas into the plasma surface treatment equipment, ionizing positive and negative charges from the second gas in the plasma surface treatment equipment, and performing surface hydrophilic modification treatment on the elisa plate to obtain the high-binding-force elisa plate. According to the invention, amino groups with positive charges are generated on the surface of the elisa plate after surface modification treatment, the hydrophobic bonds on the surface of the elisa plate are replaced by hydrophilic bonds, the surface of the elisa plate can be combined with proteins with negative charges through ionic bonds under proper buffer solution and pH value, and the elisa plate subjected to surface hydrophilic modification treatment has high sensitivity to protein in the experiment process, so that the concentration and dosage of coated protein can be reduced.

Description

technical field [0001] The invention belongs to the technical field of biological instruments, and in particular relates to a production process of a high-binding enzyme label plate. Background technique [0002] The microtiter plate is mainly used in the laboratory to carry various necessary experimental supplies, and plays a key role in conditions such as antigens, antibodies, labeled antibodies, and buffers involved in immunological reactions. And the solid-phase polystyrene surface as the carrier of the microtiter plate also plays a very important role in the adsorption of antigens, antibodies or their complexes. Antigens, antibodies, and biomolecules are adsorbed to the surface of the microtiter plate, including passive adsorption, covalent binding by introducing other active groups, and binding by hydrophilic bonds. [0003] During the experimental determination of the microplate plate, the tested specimen reacts with the antigen or antibody on the surface of the micr...
