ABSTRACT:
Antibody-mediated xenograft rejection is attenuated by (1) removing preformed antibodies to various identified carbohydrate xenoantigens from the recipient's circulation prior to transplantation by extracorporeal perfusion of the recipient's blood over a biocompatible solid support to which the xenoantigens are bound and/or (2) parenterally administering a xenoantibody-inhibiting amount of an identified xenoantigen to the recipient shortly before graft revascularization and thereafter.
