CD8b / VioBlue / REAL398
Product Details
| Description | Clone REAL398 is an antibody fragment derived from the full CD8b antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAlease Complex to bind markers with high avidity. | Clone REAL398 recognizes the human CD8b antigen, a single-pass type I membrane protein and member of the immunoglobulin superfamily, also known as T cell surface glycoprotein Lyt-3. The CD8 glycoprotein is expressed by thymocytes, mature T cells, and natural killer (NK) cells and has been implicated in the recognition of monomorphic determinants on major histocompatibility complex class I antigens, and in signal transduction during the course of T cell activation. Both human and rodent CD8 antigens are comprised of two distinct polypeptide chains, alpha and beta. Most of peripheral blood CD8+ T lymphocytes express the CD8a/CD8b heterodimer, while CD8+CD16+ natural killer cells and CD8+ T cell receptor gamma/delta+ T lymphocytes express only the CD8a/CD8a homodimer. CD8b can therefore be used to selectively bind to CD8+ T cells while excluding CD8+ NK cells. | The REAlease Kits consist of the respective fluorochrome-conjugated REAlease Complexes and the REAlease Support Kit for removal of the REAlease Complexes and optional relabeling with different fluorochrome-conjugated REAlease Complexes. | |

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.
