  • 常规说明

    Antibodies produced from cDNA: Conventional technologies usually either generate antibodies against purified proteins, or against synthetic peptides based on amino acid sequences derived from DNA sequence data. Genetic immunization involves introducing the gene in the form of a cDNA directly into an animal which translates this cDNA into protein thus stimulating an immune response against the foreign protein. Although the synthetic peptide approach is comparable in speed, the quality of antibodies generated by genetic immunization is far superior. This is because the protein is made by the immunized animal, utilzing complex cellular mechanisms that allow it to gain a native conformation. Antibodies are then generated against a native protein, such as is found in the blood or tissues of its host species. Membrane-bound or secreted proteins often create problems for conventional antibody technology because in their native form, they are often modified by glycosylation, or in some cases exist as multiple membrane-spanning proteins that are not soluble following isolation or synthesis in recombinant systems. All of these problems are avoided if the immunized animal makes the protein itself. Antibodies generated by genetic immunization have been shown to have binding affinities to the protein in the sub-nanomolar range, which are approximately 100x higher than conventionally developed antibodies and much higher than single chain antibodies. Results confirm published data for much higher avidity of sera generated by genetic immunization as compared with that gained by immunization with a corresponding recombinant protein.

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing this with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    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.

Question

Hello, I am searching a CEACAM antibody that can detect CEACAM on MDCK cells, which come from dog kidney. I am wondering if by immunogen peptied homology comparison it is possible to find one antibody that is suitable for dog CEACAM1 or other more common CEACAMs. Would some anti-human pan CEACAM work on dog CEACAMs? I would very much appreciate it if you can help me pick up the right antibody.

Answer

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.
