General description

CEACAM1 (carcinoembryonic antigen-related cell adhesion molecule 1) is thought to be a member of the immunoglobulin superfamily and is known as an epithelial tumor suppressor and an angiogenic growth factor. It has also been linked to the actin-based cytoskeleton. CEACAM1 is also known as a cellular receptor for a number of human mucosa pathogenic bacteria. The loss of activity of CEACAM1 has been related to the development of colorectal cancer.

Immunogen

Recombinant human CEACAM1/CD66a.

Flow Cytometry Analysis: A representative lot detected CEACAM1/CD66a expression on the surface of 2 day-starved human epithelial (HT29, T102/3) and endothelial (AS-M.5) cells, as well as multivesicular bodies (MVBs) derived from these cells (Muturi H.T., et al. (2013) PLoS One. 8(9):e74654).

Immunocytochemistry Analysis: A representative lot detected CEACAM1/CD66a immunoreactivity on the surface of normal human bronchial epithelial (NHBE) cells by indirect immunofluorescence staining (Klaile, E., et al. (2013) Respir Res. 14:85).

Immunohistochemistry Analysis: A representative lot detected CEACAM1/CD66a in paraffin-embedded human lung cancer tissue sections (Klaile, E., et al. (2013) Respir Res. 14:85).

CEACAM5 is overexpressed in many primary breast carcinomas. However, the exact role of CEACAM5 in breast cancer tumorigenesis remains unresolved. Here, we examined a repository of 110 cryopreserved primary breast carcinomas by immunohistochemistry to assess the distribution of CEACAM5 in
