Anti-CEACAM1 Antibody

A rabbit polyclonal primary antibody from Antibodies.com targets human CEACAM1, a cell-surface glycoprotein belonging to the carcinoembryonic antigen family that mediates intercellular adhesion, angiogenesis, and innate immune signaling. The 100 µl vial ships unconjugated and ready for direct incorporation into western blot and immunohistochemistry workflows on human tissue sections and cultured cell-line lysates. Polyclonal clonality enables recognition of multiple epitopes across the extracellular Ig-like domains of CEACAM1.

Investigators studying colorectal tumor biology, vascular remodeling, and immune-cell signaling use this reagent to localize CEACAM1 expression in formalin-fixed paraffin-embedded biopsies and to evaluate endogenous protein levels by western blot. Recommended handling includes refrigerating the vial on arrival, aliquoting to limit freeze-thaw cycles, and protecting it from light during extended storage. The product is supplied for research use only and is not validated for diagnostic or therapeutic applications.
