A comparison of two techniques for the detection of an antibody in human serum to Chang liver cell surface antigens.
The antibody-dependent cell-mediated cytotoxicity technique (ADCC) and an isotopic antiglobulin technique have been compared for their abilities to detect human serum antibodies to Chang liver cell membrane antigens. The optimal conditions were established for the latter technique, which was found to be superior with respect to reproducibility and sensitivity. Also, unlike ADCC, the isotopic antiglobulin technique was unaffected by other factors, such as immune complexes present in pathological sera.
