CARRIER OF ANTIGEN OR ANTIBODY

摘要

A highly sensitive immunoassay agent can be obtained from a small amount of an antigen or antibody by fixing the antigen or antibody on a solid support in a solution in the presence of a protein different from said antigen or antibody. Suitable proteins are 1) serum proteins such as bovine serum albumin, human immunoglobulin and rabbit immunoglobulin; 2) sera themselves such as human serum and fetal calf serum and 3) other proteins such as human liver ferritin and human recombinant gamma interferon. Bovine serum albumin is especially preferable.
