CD8a / VioBlue / REAL137
Product Details
| Description | Clone REAL137 is an antibody fragment derived from the full CD8a 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 REAL137 is specific for the mouse CD8a antigen, also known as LY-2 or T8, which is expressed on cytotoxic T cells and at lower levels on subpopulations of dendritic cells and TCRgamma/delta+ cells. CD8a is further detected on most thymocytes (CD4+CD8a+ and CD4–CD8+ thymocytes). Cytotoxic T cells and thymocytes express CD8a as heterodimer with CD8b, whereas dendritic cells and TCRgamma/delta+ cells express a CD8a/CD8a homodimer. It mediates efficient cell-cell interactions within the immune system. | 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 CD8a
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 acts as a coreceptor with the T-cell receptor on the T lymphocyte to recognize antigens displayed by an antigen presenting cell in the context of class I MHC molecules. The coreceptor functions as either a homodimer composed of two alpha chains or as 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 alpha chain. Multiple transcript variants encoding different isoforms have been found for this gene. The major protein isoforms of this gene differ by the presence or absence of a transmembrane domain and thus differ in being a membrane-anchored or secreted protein. [provided by RefSeq, May 2020]
