Human NKG2A&CD94 Protein, Fc Tag

  • Synonym
    NKG2A & CD94
  • Source
    Human NKG2A&CD94, Fc Tag (NC4-H5257) is expressed from human 293 cells (HEK293). It contains AA Ala 113 - Leu 233 (NKG2A) & Asp 57 - Ile 179 (CD94) (Accession # P26715-1(NKG2A) & Q13241-1(CD94)).
    Predicted N-terminus: Ala 113
  • Molecular Characterization

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 55.1 kDa. The protein migrates as 60-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Immobilized Human NKG2A&CD94, Fc Tag (Cat. No. NC4-H5257) at 2 μg/mL (100 μL/well) can bind Anti-NKG2A Antibody, Human IgG1 with a linear range of 0.1-8 ng/mL (QC tested).

  • Background
    CD94 plays a role as a receptor for the recognition of MHC class I HLA-E molecules by NK cells and some cytotoxic T-cells. KLRD1 (CD94) is an antigen preferentially expressed on NK cells and is classified as a type II membrane protein because it has an external C terminus. NKG2A/CD159a is a transmembrane protein belonging to the CD94/NKG2 family of C-type lectin-like receptors that inhibits innate immune system activation. CD94 pairs with the NKG2 molecule as a heterodimer. The CD94/NKG2 complex, on the surface of natural killer cells interacts with Human Leukocyte Antigen (HLA)-E on target cells.
