IMMUNOASSAY METHOD AND IMMUNOASSAY REAGENT

摘要

PROBLEM TO BE SOLVED: To provide a method of promoting a reaction between an antigen and an antibody without greatly increasing the background.SOLUTION: Under the coexistence of 1-50 mM amino acid (preferably, an asparaginic acid or glutamic acid as an acidic amino acid), an antigen or antibody in a sample is made to react with an antibody or antigen immobilized in an insoluble carrier. The immunoassay reagent includes an antibody or antigen immobilized in the insoluble carrier and an amino acid, and is freeze-dried.
