Anti-CD66e Antibody

Raised in rabbit, this unconjugated polyclonal reagent from Antibodies.com targets CD66e, also called CEA (carcinoembryonic antigen), a GPI-anchored cell-surface glycoprotein of the immunoglobulin superfamily that mediates homotypic and heterotypic adhesion between epithelial cells. The Primary Antibodies reagent is supplied at 100 µL per vial and is validated for Western blot, immunohistochemistry, and immunofluorescence workflows on human tissue sections, cell preparations, and lysates. CD66e is best known clinically as a circulating tumor marker for colorectal adenocarcinoma, and it is also expressed by epithelial-derived cancers of the stomach, pancreas, breast, and lung, supporting oncology pathology research, biomarker validation studies, and investigations of cell-adhesion signaling. Because the antiserum is polyclonal and unconjugated, it can be paired with secondary reporters of the researcher's choice for fluorescence, chromogenic, or chemiluminescent detection. Aliquot upon arrival and store refrigerated to preserve antibody activity across multiple experiments. Intended for research use only.
