  • Molecular Characterization

    NKG2A Structure

    Other Tags and Version Biotin & Other Labeled Version

    This protein carries a polyhistidine tag at the N-terminus.

    The protein has a calculated MW of 17.9 kDa. The protein migrates as 30-40 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin

    Less than 1.0 EU per μg by the LAL method / rFC method.

  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

    I used this recombinant protein to test function of a gRV transduction on iPS-derived cells. The product went into solution quickly during reconstitution and provided expected results from positive controls and testing samples. Signal was clear on a flow cytometry based readout using Streptavidin-Brilliant Violet 711. I used this at 5 ug at a concentration of 100 ug/mL on 50,000 total cells. No support was needed, as the provided data sheet and CoA are thorough and easy to follow. Very satisfied with my experience.

Background

NKG2A/CD159a is a transmembrane protein belonging to the CD94/NKG2 family of C-type lectin-like receptors that inhibits innate immune system activation, also known as KLRC1, CD159a, NK cell receptor A and NKG2-A/NKG2-B type II integral membrane protein. NKG2A marks a unique immune effector subset preferentially co-expressing the tissue-resident CD103 molecule, but not immune checkpoint inhibitors. NKG2A blockade therapy operated through CD8 T cells, but not NK cells. The increase in NKG2A expression might be induced by IL-10, which was present at a high level in the plasma of HCC patients. Blocking IL-10 could specifically inhibit NKG2A expression in NK cells. These findings indicate that NKG2A expression is influenced by factors from cancer nests and contributes to NK cell exhaustion, suggesting that NKG2A blockade has the potential to restore immunity against liver tumors by reversing NK cell exhaustion.
