摘要

Specific antibodies against ceramid monohexosice (CMH), ceramide dihexoside (CDH) and ceramide trihexoside (CTH) were purified from antiserum or normal (unimmunized) rabbit serum by using liposomes as immunoadsorbents. Purified antibodies were compared with whole antiserum, or immunologically reactive normal rabbit serum, for specific activity against the immunizing antigen, and cross-reactivity with the other haptens. High levels of reactivity and reciprocal cross-reactivity were observed both with antisera and purified antibodies CMH and CDH. In contrast, although anti-CMH and anti-CDH sera both apparently cross-reacted' with CTH the purified antibodies in each case did not have any detectable cross-reactivity with CTH. Conversely, anti-CTH antiserum apparently cross-reacted with CDH, whereas purified antibodies did not. It was concluded that rabbit antiserum sometimes may contain naturally-occurring antibodies against a glycosphingolipid, and these may be eliminated by using purified non-cross-reacting antibodies. Naturally-occurring antibodies against CDH and CTH, but not abainst CMH were found in 10 normal rabbit sera. Purified naturally-occurring anti-CDH antibodies obtained from ofe of these rabbits did not cross-react with CTH, but purified anti-CTH from the same rabbit did cross-react with CDH.
