HLA-E antibody

Catalog No. ABIN94352

Product Details anti-HLA-E Antibody

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: Western Blotting (WB), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Specificity: The antibody MEM-E/02 specifically reacts with an extracellular epitope on denaturated heavy chain of human HLA-E. HLA-E belongs to the MHC Class I molecules (MHC Class Ib, nonclassical) and it is expressed on the surface of all human cell types.

Cross-Reactivity (Details): Human, Non-Human Primates

Purification: Purified by protein-A affinity chromatography.

Purity: > 95 % (by SDS-PAGE)

Immunogen: Recombinant human HLA-E denaturated heavy chain.

Clone: MEM-E-02

Isotype: IgG1

Application Details

Application Notes: Immunohistochemistry (paraffin sections): Recommended dilution: 5-10 μg/mL, positive control: human placenta, heat antigen retrieval (sodium citrate), incubation with mAb: 1 hour / RT, detection DAB.

Target Details for HLA-E

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

Alternative Name: HLA-E (HLA-E Products)

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
