Immunochemical Studies on Blood Groups

[摘要] 1. 1. Preparations of B substance from human saliva varied in the amount of anti-B precipitable from an anti-B serum produced by isoimmunization of pregnancy although all of their hexosamine was specifically precipitable by excess antibody.2. 2. B preparations from 2 horses also precipitated this anti-B and were shown by hexosamine analyses to be of comparable purity to the human saliva substances. Horse substances with little or no B activity by hemagglutination inhibition tests precipitated a portion of the anti-B from this antiserum.3. 3. B substance from pseudomucinous ovarian cyst and a bovine stomach B substance precipitated less antibody from this antiserum and only about one-half of their hexosamine could be specifically precipitated by anti-B.
