Anti-CD276 antibody produced in rabbit

CD276 (cluster of differentiation 276) is a member of the B7 family of T cell co-regulatory molecules, which functions as an immune-regulatory molecule. This protein is inducible by inflammatory cytokines on T-cells, B-cells and dendritic cells. Its ligand is yet unidentified.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

CD276 (cluster of differentiation 276) functions as both T-cell stimulatory and inhibitory protein in tumor cells, and hence, its function in tumors is not very clear. In CRC (colorectal cancer), the expression of this protein has a strong and independent relation with poor prognosis. The expression of this protein is highly increased in endothelial cells (ECs) in cancer as opposed to that in normal tissue. Also, the number of circulating ECs is increased in tumor conditions as compared to normal conditions. CD276 is also up-regulated in glioblastomas, breast, lung, renal and colon carcinomas. It is a putative biomarker for rheumatoid arthritis (RA), and B7-H3-T-A-C-T polymorphism is linked to increased RA risk. This variant might also be linked to the secretion of soluble B7-H3. CD276 promotes tumorigenesis of mantle cell lymphoma, and its inactivation leads to increased sensitivity to chemotherapy.

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
