Overview

  • Product nameAnti-HLA E antibody [MEM-E/07]
    See all HLA E primary antibodies
  • Description
    Mouse monoclonal [MEM-E/07] to HLA E
  • SpecificityThe antibody recognized native surface-expressed HLA E, but not denaturated heavy chain of HLA E. The published results revealed that the antibody cross-reacts with some classical MHC Class I molecules: HLA B7 (strongly), HLA B8 (moderately), HLA B27, HLA-B44 (weakly).
  • Tested applicationsSuitable for: WB, ICC/IF, Flow Cyt, IPmore details
  • Species reactivity
    Reacts with: Human
  • Immunogen

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

Target

  • RelevanceHLA E belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). The heavy chain is anchored in the membrane. HLA E binds a restricted subset of peptides derived from the leader peptides of other class I molecules.

Anti-HLA E antibody [MEM-E/07] images

  • ab11820 staining HLA E in Human endothelial cell line by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 5% BSA for 2 hours at 4°C. Samples were incubated with primary antibody (1/100 in 5% BSA in PBS with 0.1% Triton X-100) for 1 hour at 4°C. An undiluted FITC-conjugated Goat anti-mouse polyclonal was used as the secondary antibody.

  • Cells were treated with 500 Units of human IFN-gamma on 1 million ECV304 cells after 36 hours cells were harvested (PVG 0.1% trypsin), fixed with 2% paraformaldehyde and surface staining of HLA E was performed using ab11820 at a 1/100 dilution. The secondary used was a goat anti-mouse-FITC, at a 1/100 dilution.
    Red line indicates the untreated expression level and black indicate the induced surface expression of HLA E. Gating strategy - total population.

    HLA-G– or HLA-E–expressing HeLa cells were transfected with HCMV endoplasmic reticulum resident transmembrane glycoprotein US10. The lysates were immunoblotted with antibodies against HLA-G, HLA-E (ab11820), or beta-actin as a loading control. The figure shows that expression of HLA-G is slightly reduced by US10.
