CD66e antibody; CEACAM5 antibody; DKFZp781M2392 antibody; CEA antibody; CD66e antibody; Psg30 antibody; 1600029H12Rik antibody; CEA antibody
This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human CEACAM5 / CD66e (rh CEACAM5 / CD66e; NP_004354.2; Met 1-Ala 685). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.

CEACAM5 / CD66e Antibody, Mouse MAb, Immunohistochemistry
Immunochemical staining of human CEACAM5 in human rectal cancer with mouse monoclonal antibody (15 µg/mL, formalin-fixed paraffin embedded sections). Positive staining was localized to intestinal gland.
CEACAM5, also known as CEA or D66e, belongs to the large CEACAM subfamily of immunoglobulin superfamily. CEACAM5 is expressed primarily by epithelial cells, and is synthesized as a glycoprotein with a MW of 180 kDa comprising 60% carbohydrate. CEACAM5 contains one Ig-like V-type domain at the N-terminus, followed by six Ig-like C2-type domain and a GPI anchor, and exists as a homodimer. CEACAM5 and CEACAM6 are overexpressed in many cancers and are associated with adhesion and invasion. CEACAM5 can mediate cell-cell adhesion through homotypic and heterotypic interactions. It functions as a homotypic intercellular adhesion molecule and serves as a widely used tumor marker, since it is expressed at higher levels in tumorous tissues than in corresponding normal tissues. CEACAM5 has also been shown to contribute to tumorigenicity by inhibiting cellular differentiation. In addition, CEACAM5 is identified as the host receptor for the Dr family of adhesins of E.Coli, and the binding of E.coli Dr adhesins leads to dissociation of the CEACAM5 homodimer.
