Abstract
Immunoconjugates of an antibody to a 22 KD breast tumor associated antigen were prepared. Cytotoxic immunoconjugates such as gelonin-15A8 antibody conjugate are useful for treating proliferative cell diseases such as breast carcinoma and cervical carcinoma as well as other tumors which bear the 15A8 antigen. Detectably labeled compositions for diagnosis of such diseases are also disclosed.
Claims4
