Quick Overview for HLA-E antibody (ABIN94354)

Target: HLA-E (HLA Class I Histocompatibility Antigen, alpha Chain E (HLA-E))

Reactivity: Human, Non-Human Primate

Host: Mouse

Clonality: Monoclonal

Conjugate: This HLA-E antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunoprecipitation (IP), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Clone: MEM-E-06

Product Details anti-HLA-E Antibody

Purpose: Anti-HLA-E Purified

Specificity: The antibody MEM-E/06 recognizes an extracellular epitope on native surface-expressed HLA-E, but not denaturated heavy chain of HLA-E. HLA-E belongs to the MHC Class I molecules (MHC Class Ib, nonclassical) and it is expressed on many types of the human cells. The published results showed that the antibody cross-reacts with some classical MHC Class I molecules (HLA-A3, -A11, -B7). However, the recent Workshop I Session on the 3rd International Conference on HLA-G (Paris, July 2003) confirmed that the antibody exhibits much broader cross-reactivity classical MHC Class I antigens, namely with HLA-A24, -A32, -B8, -B15, -B27, -B35, -B44, -B54, -C3, -C4, -C5, -C7.

Target Details for HLA-E

Target: HLA-E (HLA Class I Histocompatibility Antigen, alpha Chain E (HLA-E))

Alternative Name: HLA-E

Background: Major histocompatibility complex, class I, E,HLA-E (human leukocyte antigen E) is a non-classical MHC I antigen, which is important for dialogue with NK cells and their regulation through interaction with CD94/NKG2 receptor. Like other MHC I molecules, transmembrane HLA-E molecule (45 kDa) associates with beta2 microglobulin. Unlike HLA-G, expression of HLA-E molecules is not so restricted, but it has been detected at least at mRNA level in virtually all cells and tissues examined. In peripheral blood, HLA-E protein is expressed at least in all mononuclear cells, but in different quantity (B cells and monocytes more than T cells and NK cells).,HLA class I histocompatibility antigen, alpha chain E, MHC class I antigen E
