Anti-CEACAM5 Antibody

The CEACAM5 antibody from Antibodies.com is a rabbit polyclonal reagent validated for Western blot and immunohistochemistry on human samples. CEACAM5, also known as CEA or carcinoembryonic antigen, is a GPI-anchored cell-surface glycoprotein of the immunoglobulin superfamily that has long served as a clinical tumor marker in colorectal, gastric, pancreatic, and non-small cell lung cancers. Researchers use this unconjugated antibody to probe CEACAM5 expression in formalin-fixed paraffin-embedded tumor sections and to detect the protein in cell lysates by Western blot.

Each vial contains 100 µl of antibody at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a stabilizing cryoprotectant, supporting convenient storage at -20 °C and protection from repeated freeze-thaw cycles. The reagent is supplied as a polyclonal blend raised against human CEACAM5 and is intended for research use only, including studies of epithelial differentiation, tumor progression, and biomarker validation in cultured cell samples and tissue microarrays.
