Antigen-antibody analysis with solid phase RF and C1q

摘要

Biological fluids, such as serum, are analyzed for the presence, nature and/or amount of antibodies, antigens and antibody:antigen complexes therein using as a reagent, insolubilized rheumatoid factor or insolubilized C1q. These reagents are themselves novel. They bind to antibody: antigen complexes, but not to free antibodies or antigens, and complexes can thus be removed from mixtures thereof with other materials, such as antibodies and antigens.
