Anti-CEACAM-1 (CEACAM-1, Carcinoembryonic Antigen-related Cell Adhesion Molecule 1, BGP1, CD66a, Cea

CEACAM-1 (Carcinoembryonic antigen-related cell adhesion molecule 1, also known as BGP1, CD66a, and MHVR1) is a 110-120kD member of the CEACAM subfamily and the CEA family of proteins. It has a wide expression pattern, being found on neutrophils, dendritic cells, endothelial cells, colonic epithelium, and hepatocytes. It mediates cell adhesion, and appears to regulate insulin levels and signaling by interacting with the insulin receptor. It also demonstrates pro-angiogenic effects by inducing endothelial cells to proliferate and form capillary-like tubules. Finally, CEACAM-1 is a known receptor for mouse hepatitis virus. Mature mouse CEACAM-1 is a 487 amino acid (aa) type I transmembrane glycoprotein. It contains a 394 aa extracellular region (aa 35-428) that shows one V-type (aa 35-142) and three C2-type (aa 147-411) Ig-like domains, plus a 74 aa cytoplasmic domain. Three alternate splice forms exist. One contains a four aa substitution for aa 455-521, a second shows a Gln substitution for aa 142-322, and a third possesses a combination of the first two splice patterns. CEACAM-1 forms homodimers. Over aa 35-428, mouse CEACAM-1 shares 56% and 70% aa identity with human and rat CEACAM-1, respectively. Applications: Suitable for use in Flow Cytometry. Other applications not tested. Recommended Dilution: Flow Cytometry: 10ul, 1x10e6 cells, Optimal dilutions to be determined by the researcher. Hybridoma: Mouse myeloma cells with B cells from Balb/c rats. Storage and Stability: May be stored at 4°C before opening. DO NOT FREEZE! Stable at 4°C as an undiluted liquid. Dilute only prior to immediate use. Stable for at 12 months at 4°C. Freezing allophycocyanin conjugates will result in a substantial loss of activity. Allophycocyaninconjugates are sensitive to light.
