Carcinoembryonic Antigen (CEA) / CD66; Clone SPM330 (Concentrate)
Immunogen: Purified human CEA protein
Isotype: IgG1, kappa
Species Reactivity: Human and Monkey. Others not known.
Positive Control: MCF7 or 293T cells. Colon carcinoma
Specificity: This antibody recognizes proteins of 80-200kDa, identified as different members of CEA family, and is re-expressed in increased amounts in intestinal carcinomas and several other tumors. This MAb reacts with nonspecific cross-reacting antigen (NCA) and shows a cross-reaction with human polymorphonuclear leucocytes. It shows no reaction with a variety of normal tissues and is suitable for staining of formalin/paraffin tissues.
