Enzyme-Linked Immunosorbent Assay

Enzyme-linked immunosorbent assay service is a special reagent analysis method, which is a new type of immunoassay technology developed on the basis of immunoenzymatic techniques. CD BioSciences provides professional enzyme-linked immunosorbent assay services to meet the specific needs of different customers. If you have any needs in this regard, please feel free to contact us.


  • The antigen or antibody is bound to the surface of a certain solid-phase carrier and its immune activity is maintained.
  • Link the antigen or antibody with a certain enzyme to form an enzyme-labeled antigen or antibody. This enzyme-labeled antigen or antibody retains its immune activity and enzyme activity. In the measurement, the test specimen (the antibody or antigen in the measurement) and the enzyme-labeled antigen or antibody are reacted with the antigen or antibody on the surface of the solid-phase carrier in different steps.

ELISA can be used for the determination of antigens and antibodies. There are 3 necessary reagents in this determination method:

  • A solid phase antigen or antibody
  • Enzyme-labeled antigen or antibody
  • Substrate for enzyme action (color developer). According to the source of the reagents, the properties of the specimens and the testing conditions, various types of testing methods can be designed.
