Specificities of Human Antibodies to Australia Antigen

Abstract

SummaryNine different human anti-Australia antigen antisera were compared to each other using population and immunologic methods. Six of the antisera fell into the same category (Philadelphia I) and included specificities detected by the previously described anti-Au(1) antisera. There were three antisera, each of which contained specificities different from those in the anti-Au(1) category. They are to be examined to see whether they identify forms of hepatitis or other conditions different from those detected by anti-Au(1).
