Non unique reaction absorbent null for converse passive cohesion reaction

摘要

PURPOSE:To suppress the generation of non-specific reaction by utilizing a monoclonal antibody which is drived from the same kind of an animal and is an antigen different from the antigen of a measuring object. CONSTITUTION:The monoclonal antibody to be utilized for a non-specific reaction absorbent is derived from the same kind of the animal for the monoclonal antibody sensitized with carrier particles to be subjected to agglutination reaction and is the antigen different from the antigen of the measuring object. The specificity of the antigen is not known but the monoclonal antibody derived from myeloma is also included in the monoclonal antibody of this invention. The monoclonal antibody of this invention is satisfactorily usable as the non- specific reaction absorbent even as it is and the non-specific reaction absorptive power is improved by subjecting the antibody to a modification treatment when the rheumatoid factors, etc. are contained in the specimen.
