ABSTRACT:
The present invention provides a method, and resulting product, for the removal of unwanted molecules from a host's blood using a one-step procedure. The unwanted molecules may be anti-A blood protein and/or anti-B blood protein antibodies that would otherwise cause host rejection of transplanted organs or tissues from a source having a different ABO blood type. The unwanted molecules may also be excess antibodies, or virions, present in a diseased host.
