CD8a Rat anti-Canine, eFluor® 450, Clone: YCATE55.9, eBioscience
Rat Monoclonal Antibody
Manufacturer: Invitrogen 48508042
Description: This YCATE55.9 monoclonal antibody reacts with canine CD8 alpha. This cell surface receptor is expressed either as a heterodimer with the CD8 beta chain (CD8 alpha/beta) or as a homodimer (CD8 alpha/alpha). In dogs, CD8 alpha is expressed on thymocytes, a subset of mature T cells, NK cells, and intestinal intraepithelial lymphocytes (IELs). CD8 binds to MHC class I and plays a role in thymocyte development and mature T cell activation. This monoclonal antibody has been reported to inhibit cytotoxic T cell generation and function in vitro. In addition, this antibody has been reported to be immunosuppressive in vivo. Applications Reported: This YCATE55.9 antibody has been reported for use in flow cytometric analysis. Applications Tested: This YCATE55.9 antibody has been pre-titrated and tested by flow cytometric analysis of normal canine peripheral blood cells. This can be used at 5 µL (0.5 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. eFluor® 450 is an alternative to Pacific Blue®. eFluor® 450 emits at 445 nm and is excited with the Violet laser (405 nm). Please make sure that your instrument is capable of detecting this fluorochome. Excitation: 405 nm; Emission: 445 nm; Laser: Violet Laser. Filtration: 0.2 µm post- manufacturing filtered. CD8 (Cluster of Differentiation 8) is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediate efficient cell-cell interactions within the immune system. The CD8 antigen acts as a co-receptor with the T-cell receptor on the T lymphocyte to recognize antigens displayed by an antigen presenting cell (APC) in the context of class I MHC molecules. CD8 is found on a T cell subset of normal cytotoxic/suppressor cells which make up approximately 20-35 % of human peripheral blood lymphocytes. The CD8 antigen is also detected on natural killer (NK) cells, subpopulations of peripheral blood null cells, thymocytes and bone marrow cells. The CD8 co-receptor functions as either a homodimer composed of two alpha chains, or as a disulfide-linked heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains. The majority of CD8+ T cells express CD8 as a alpha/beta heterodimer. In HIV, the HIV-2 envelope glycoprotein binds CD8 alpha chain (but not the beta chain).
