HIGHLY REPRODUCIBLE AGGLUTINATION IMMUNOASSAY METHOD AND REAGENTS

摘要

A highly reproducible agglutination immunoassay method wherein the agglutination of insoluble carrier particles (latex, etc.) is stabilized and uniformized and immunoassay reagents to be used therein. In an agglutination immunoassay method comprising bonding an antigenic substance in a test sample to insoluble carrier particles, to which neither an antigen nor an antibody is substantially bonded, and then bonding an antibody or an antibody complex specifically reacting with the antigenic substance thereto to thereby selectively agglutinate the insoluble carrier particles, use is made of a polymer formed by homopolymerizing a monomer having phosphorylcholine and vinyl groups (for example, 2-methacryloyloxyethylphosphorylcholine) or copolymerizing such a monomer having phosphorylcholine and vinyl groups with another monomer having vinyl group (for example, n-butyl methacrylate).
