  • Analysis of biological fluids
    Patent number: 4283383
    Abstract: 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 Clq. 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.
    Type: Grant
    Filed: September 27, 1978
    Date of Patent: August 11, 1981
    Assignee: Technicon Instruments Corporation
    Inventors: Pierre L. Masson, Joseph F. Heremans
