IMMUNOASSAY USING ANTIBODY-ANTIGEN CONJUGATES

摘要

A novel immunoassay technique is provided which is useful in the detection and determination of antibodies to antigens. Antibodies of all classes to a given antigen or the specific subclass of immunoglobulin to a specified antigen can be detected. A conjugate of labelled antibody and specific antigen is used as the third reagent in a sandwich assay.
