摘要

An objective of the present invention is to provide an anti-human IgM monoclonal antibody that is capable of reacting specifically with human IgM and inducing immunoagglutination based on an antigen-antibody reaction with human IgM in solution, and an immunoassay using the said monoclonal antibody. Another objective of the present invention is to provide an agent for suppressing non-specific reactions caused by human IgM that could not be prevented by conventional methods, and an immunoassay in which non-specific reactions caused by human IgM are suppressed. By selecting a monoclonal antibody that reacts with human IgM on the basis of evaluation of reactivity with human IgM in solution, a novel monoclonal antibody capable of agglutinating human IgM by itself and performing a practical immunoagglutination assay has been obtained, and the objectives above have been thus achieved.
