Anti-CEACAM5 Antibody

CEACAM5 (also known as CEA, Carcinoembryonic Antigen) is a heavily glycosylated cell-surface adhesion molecule of the immunoglobulin superfamily that has been studied extensively as a clinical tumor marker. Raised in rabbit, this polyclonal antibody recognizes human CEACAM5 and is supplied as 100 µl of unconjugated reagent in a single-use vial, validated for Western blot and immunohistochemistry workflows.

Typical research uses include profiling CEACAM5 expression in colorectal, gastric, pancreatic, non-small cell lung, and breast adenocarcinoma tissues and cell lines, where the antigen is frequently overexpressed and associated with epithelial differentiation and metastatic behavior. For best stability, store the vial at -20°C in working aliquots and avoid repeated freeze-thaw cycles; thaw aliquots on ice immediately before use and keep diluted preparations refrigerated for short-term use only.

Researchers should consult the lot-specific data sheet shipped with the product from Antibodies.com for recommended starting dilutions, antigen retrieval conditions for formalin-fixed sections, and compatible secondary reagents. This reagent is for research use only and is not validated or intended for diagnostic, prognostic, or therapeutic applications.
