Abstract
PFc' fragments (corresponding to homology region Cγ3) and smaller subfragments produced by trypsin and papain have been studied by haemagglutination inhibition techniques for the presence of a range of Fcγ allotypic markers. The markers which were identified in the pFc' fragment included Gm(a), (x), (b0), (b3), (b4), (b5), (c3), (c5) and `non a'. In addition, an IgG 4 marker which possibly occupies the same molecular region as the Gm(a) and `non a' antigens was detected in pFc' fragments from IgG 4 proteins.
