Anti-Carcinoembryonic Antigen Antibody

The Antibodies.com Anti-Carcinoembryonic Antigen polyclonal antibody recognizes human CEACAM5, an approximately 180 kDa GPI-anchored cell-surface glycoprotein of the immunoglobulin superfamily. CEACAM5 mediates homotypic cell-cell adhesion and is routinely monitored as a tumor marker in colorectal adenocarcinoma and other epithelial carcinomas, making this reagent relevant to oncology and cell biology research.

Provided as 100 µg of unconjugated rabbit IgG in liquid form, the antibody is validated for Western blot and immunocytochemistry on human cells and tissues. Researchers commonly use it to confirm CEA overexpression in cultured carcinoma lines and to localize the antigen in fixed-cell preparations. For optimal stability, store the vial at -20 °C in working aliquots, protect from light, and minimize freeze-thaw cycles; briefly thawed material can be kept refrigerated at 4 °C for short-term use.
