HLA-E antibody

Catalog No. ABIN302071

Product Details anti-HLA-E Antibody

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

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This HLA-E antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunoprecipitation (IP)

Specificity: The antibody MEM-E/08 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 revealed that antibody is remarkably specific for HLA-E, only with weak cross-reactivity with following classical MHC Class I molecules (MHC Class Ia): HLA-A24, -B7, -B27, -B51, -B54, -C7.

Cross-Reactivity (Details): Human

Purification: Purified by protein-A affinity chromatography.

Purity: > 95 % (by SDS-PAGE)

Immunogen: Bacterially expressed recombinant HLA-E refolded with beta2-microglobulin and peptide.

Clone: MEM-E-08

Isotype: IgG1

Application Details

Application Notes: Flow cytometry: Recommended dilution: 4 μg/mL, positive control: human cell line LCL 721.221 (HLA-E transfected).

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)

Synonyms: EA1.2 antibody, EA2.1 antibody, HLA-6.2 antibody, MHC antibody, QA1 antibody, major histocompatibility complex, class I, E antibody, HLA-E antibody, PATR-E antibody

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
