Background

The enzyme label plate is a device matched with an enzyme label and used for enzyme-linked immunoassay, and although the enzyme label plate is only a common plastic plate with holes, the enzyme label plate is an indispensable part in enzyme immunoassay.

Enzyme-linked immunosorbent assay, the most widely used technique in enzyme immunoassay, is based on the principle that known antigen or antibody is adsorbed on the surface of solid phase carrier and retains its immunological activity. Then the antigen or antibody is connected with a certain enzyme to form enzyme-labeled antigen or antibody, the enzyme-labeled antigen or antibody retains its immunological activity and enzyme activity, and during the determination, the tested sample (the antibody or antigen in the determination) and the enzyme-labeled antigen or antibody are reacted with the antigen or antibody on the surface of the solid phase carrier according to different steps. The antigen-antibody complex formed on the solid phase carrier is separated from other substances by washing, and finally the enzyme quantity bound on the solid phase carrier is in a certain proportion to the quantity of the detected substance in the specimen. After the substrate of the enzyme reaction is added, the substrate is catalyzed by the enzyme to be changed into a colored product, and the amount of the product is directly related to the amount of the detected substance in the sample, so that the qualitative or quantitative analysis can be carried out according to the shade of the color reaction.
