Anti-CEACAM3 Antibody

CEACAM3 (also called CD66d) is a GPI-anchored member of the carcinoembryonic antigen family of immunoglobulin-like cell-surface receptors, expressed primarily on granulocytes where it functions as a dedicated opsonin-independent receptor for Opa-protein-bearing Neisseria gonorrhoeae and Neisseria meningitidis, triggering phagocytosis and Src-family kinase signaling. This Antibodies.com rabbit polyclonal antibody targets CEACAM3 and is supplied at 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol, packaged as a 100 µl vial of unconjugated IgG. The reagent is validated by the supplier for Western blot and immunohistochemistry and is listed as reactive with human, mouse, and rat orthologues, enabling surveys of CEACAM3 expression across myeloid cell lines, primary neutrophil lysates, and formalin-fixed paraffin-embedded tissue sections from infection and inflammation studies. Storage at -20°C in working aliquots is advised to limit freeze-thaw exposure of the glycerol-containing stock, and the sodium azide preservative is suitable for most immunoperoxidase and fluorescence detection workflows.
