Abstract

Conjugates of monoclonal antibodies specific to human melanoma and the A chain of a toxic lectin such as ricin or an equivalent ribosomal inhibiting protein. The conjugate is synthesized by a novel process employing anti-toxic lectin B chain antibodies to remove lectin B chain impurities and provide a highly purified conjugate that is non-toxic to cells other than melanoma. The conjugates are used to treat human melanoma. The hybridomas XMMME-001 and XMMME-002 were deposited with the American Type Culture Collection (A.T.C.C.) on Mar. 26, 1985, and given A.T.C.C. Accession Nos. HB8759 and HB8760, respectively.
