  • Description

    Mouse monoclonal [TET2] to pan CEACAM
  • Host species

  • Specificity

    ab26283 is a broadly reactive antibody which reacts with most of the CEACAM molecules characterized to date (except CEACAM3, CEACAM4 and CEACAM7)4. It can be used to detect CEACAM1 (BGP/CD66a), CEACAM5 (CEA/CD66e), CEACAM6 (NCA/CD66c) and CEACAM8 (CGM6/CD66b) on transiently transfected BOSC23 cells by flow cytometry.
  • Tested applications

    Suitable for: Flow Cyt, ELISA, WB, IHC-Fr, IPmore details
  • Species reactivity

    Reacts with: Human
  • Immunogen

    ab26283 was generated by immunisation of BALB/c mice with CEA partially purified from a perchloric acid extract from liver metastases of colonic tumors.

  • Relevance

    CEA-related cell adhesion molecules (CEACAM) belong to the carcinoembryonic antigen (CEA) family. It consists of seven CEACAM (CEACAM 1, CEACAM 3-CEACAM 8) and 11 pregnancy-specific glyco-protein (PSG 1-PSG 11) 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 leucocytes. Over-expression of CEA/ CEACAM 5 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 lymphocyte and dendritic cell activation, receptors of Neisseria species and other bacteria.

  • Overlay histogram showing Caco 2 cells stained with ab26283 (red line). The cells were fixed with 80% methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab26283, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

    Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.

Thank you for your inquiry. I was liaising with the laboratories to find out more about our pan-CEACAM- and CEACAM1-antibodies. Unfortunately, it turned out that we do not have any suitable antibody available: The immunogens of our CEACAM1 antibodies share a sequence homology with dog of 67% at the best. Thus, we would not predict a cross-reactivity for one of these antibodies. The same applies for our pan-CEACAM antibodies: The human CEACAM proteins used as immunogens reveal sequence similarities with the dog ortholog that are below 70%, suggesting that a cross-reactivity of the antibody is rather unlikely. If you have not done yet, I would like to recommend checking the Biocompare website which has an excellent antibody search facility that includes many suppliers. The links are: www.biocompare.com http://www.biocompare.com/ProductCategories/2045/Antibodies.html I am sorry that I could not be more helpful on this occasion and hope this information is nevertheless helpful to you. Please do not hesitate to contact me if you have any further questions in this regard.
