  • Patent number: 4487830
    Abstract: A method for the determination of autoantibody in a test sample comprises contacting a substrate for the autoantibody with sample; treating the contacted substrate with labeled antihuman antibody selected from (1) a mixture comprising enzyme labeled antihuman antibody and fluorescent labeled antihuman antibody, and (2) antihuman antibody labeled with an enzyme and a fluorescent label; determining the enzyme activity of the treated substrate; and determining the immunofluorescent patterns in substrates exhibiting enzyme activity. The method is useful for the rapid screening and characterization of autoantibodies.
