ABSTRACT:
An immunoassay element for quantitatively analyzing a ligand by determining the change in enzymatic activity caused by a reaction between the ligand, a linked product of the ligand and a high molecular weight compound 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 non-difussible material. Also provided is a process for quantitatively analyzing a ligand contained in a sample by the use of the immunoassay element.
