Biochemical and histochemical characteristics of target antigen detected by monoclonal antibody HBCA-12 against a membrane component of human mammary carcinoma cell line.
Monoclonal antibody HBCA-12 obtained by hybridoma procedure after immunization with human mammary adenocarcinoma cell line MDA-MB-231 immunoprecipitated a cell surface sialoglycoprotein gp80 (apparent molecular weight 80 000) from MDA-MB-231 cells and a glycoprotein gp78 from human myeloma cell line ARH 77. A protein of a similar electrophoretic mobility was immunoprecipitated also from 35S-methionine metabolically radiolabeled human melanoma cell line VUP 1. The expression of the antigen recognized by HBCA-12 monoclonal antibody could be detected neither on PHA-induced nor on EBV-transformed peripheral blood mononuclear cells from healthy donors.
