Abstract

Monoclonal IgM anti-erythrocyte autoantibody produced by a NZB-derived hybridoma has been found to react with trimethylammonium-containing compounds. Such compounds are able to prevent the lysis of bromelain-treated mouse erythrocytes (BrMRBC) by those autoantibodies. Using a column of insolubilized betaine hydrazine (BH) the monoclonal anti-erythrocyte antibody has been specifically retained. Elution of this antibody was accomplished by 0.15 M choline (Ch).
