| Scientific Background: | CEA-related cell adhesion molecules (CEACAM) belong to the carcinoembryonic antigen (CEA) family. It consists of seven CEACAM (CEACAM1, CEACAM3-CEACAM8) and 11 pregnancy-specific glycoprotein (PSG1-PSG11) members. The CEA family proteins belong to the immunoglobulin (Ig) superfamily and are composed of one Ig variable-like (IgV) and a varying number (0-6) of Ig constant-like (IgC) domains. CEACAM molecules are membrane-bound either via a transmembrane domain or a glycosyl phosphatidyl inositol (GPI) anchor. CEACAM molecules are differentially expressed in epithelial cells or in leukocytes. Overexpression of CEA/CEACAM5 in tumors of epithelial origin is the basis of its wide-spread use as a tumor marker. The function of CEACAM family members varies widely: they function as cell adhesion molecules, tumor suppressors, regulators of lymphocytes and dendritic cell activation, receptors of Neisseria species and other bacteria. |

Specificity testing of D14HD11 (Prod. No. ALX-805-080). BOSC cells were transiently transfected with expression vectors containing either the cDNA of CEACAM1, CEACAM3, CEACAM5-CEA-CAM8 or a recombinant transmembrane-anchored PSG1 fusion protein. Recognition of CEACAM4 was tested on CHO cells stably transfected with a CEACAM4 expression vector. Expression of the constructs was confirmed with monoclonal antibodies known to recognise the corresponding proteins (CEACAM1, 3, 4, 5 and 6: D14HD11; CEACAM7: CAC2; CEACAM8: 80H3; PSG1: BAP1; green curves). An irrelevant monoclonal antibody served as a negative control (black curves). For specificity testing, protein G purified D14HD11 was tested on all CEACAM transfectants. A positive signal was obtained with CEACAM1, CEACAM3, CEACAM4, CEACAM5 and CEACAM6 expressing cells (red curves).
