发明名称 METHOD FOR MEASURING ANTIGEN-ANTIBODY REACTION
摘要 PURPOSE:To prevent an increase in the amt. of agglutination with time and to improve the accuracy of measurement by adding a reaction stopping agent to a reactive liquid mixture of the antigen or antibody corresponding to a latex deposited with an antigen or antibody and measuring the quantity of the agglutination reaction of this time. CONSTITUTION:A surfactant as the reaction stopping agent is added to the reactive liquid mixture prepd. by bonding a spacer group to latex particles and mixing the antigen or antibody with the latex having such spacer group. After the agglutination reaction is stopped by the addition of such agent, the quantity of the agglutination reaction is measured. Polystyrene, polymethyl methacrylate, etc., are used as the latex to be deposited with the antigen or antibody. The latex agglutination reaction generated by immune reaction is stopped upon lapse of arbitrary time in the measurement method and, therefore, the change of the amt. of the agglutination with time is prevented and the measurement with high accuracy is permitted.
