Immunoassay element and process for immunoassay |
摘要 |
An immunoassay element for quantitatively analyzing a macromolecular antigen by determining the change in enzymatic activity caused by a reaction between the macromolecular polymer antigen and an enzyme-labelled antibody. The immunoassay element comprises a substrate layer containing a non-diffusible substrate which forms a diffusible material in the presence of the enzyme, and a reagent layer containing a fragmenting enzyme for further fragmenting the diffusible material into a lower molecular weight product. Also provided is a process for quantitatively analyzing a macromolecular antigen in a sample by the use of the immunoassay element.
