Production of monoclonal antibody SP-21 to colon-ovarian tumor antigen, COTA.
An IgG monoclonal antibody, SP-21, directed against colon-ovarian tumor antigen, COTA, is reported. The antibody had no reactivity with CEA, normal colonic mucin, CSAp, ABO blood group antigens, or with normal human lung, liver, spleen, kidney, plasma and saliva in studies using the enzyme-linked immunoassay method (ELISA). Immunoperoxidase staining of colon, lung, kidney, and prostate cancer tissues and benign and inflammatory colon disease tissues revealed a specificity identical to that of the polyclonal (goat) anti-COTA antibodies.
