CD8b Monoclonal / VioBlue / REA222
Product Details
Description | Clone REA222 recognizes rat CD8b, a member of the immunoglobulin superfamily also known as T cell surface glycoprotein Lyt-3. CD8b is expressed on cytotoxic T cells, thymocytes, and macrophages as a heterodimer with CD8a. CD8 identifies cytotoxic/suppressor T cells that interact with MHC class I bearing targets and plays a role in the process of T cell mediated killing. Flow cytometric analysis showed that CD8 T cells from lymph nodes or spleen of normal rats almost exclusively express the alpha/beta heterodimer, regardless of the T cell receptor isotype. In contrast, natural killer cells carry only CD8a chains. | Additional information: Clone REA222 displays negligible binding to Fc receptors. | | |

About CD8b
The CD8 antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. The CD8 antigen, acting as a coreceptor, and the T-cell receptor on the T lymphocyte recognize antigens displayed by an antigen presenting cell (APC) in the context of class I MHC molecules. The functional coreceptor is either a homodimer composed of two alpha chains, or a heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains. This gene encodes the CD8 beta chain isoforms. Multiple alternatively spliced transcript variants encoding distinct membrane associated or secreted isoforms have been described. A pseudogene, also located on chromosome 2, has been identified.
