Title:

CARRIER LATEX FOR DIAGNOSTIC REAGENT

Document Type and Number:

WIPO Patent Application WO/1988/002119

Kind Code:

A1

Abstract:

A carrier latex for diagnostic reagent, which comprises a suspension of particles of aromatic vinyl compound-grafted ethylene-alpha,beta-ethylenically unsaturated carboxylic acid (salt) copolymer having carboxyl groups on their surface. When used as an immunoserologically diagnostic latex utilizing antigen-antibody reaction, the latex markedly reduces nonspecific agglutination which has heretofore been problematic and, at the same time, enhance the sensitivity of the specific agglutination, thus being optimally adapted for an immunoserologically diagnostic system based on optical measurement.
