NKG2A, also known as CD159a, is a type II transmembrane receptor having a single extracellular lectin-like domain and a cytoplasmic ITIM motif. It associates with CD94 and is expressed on NK cells and some activated T cell populations. The NKG2A/CD94 complex delivers an inhibitory signal upon recognition of its ligand, HLA-E.

HEK293 Human embryonic kidney cell line transfected with either (A) Human NKG2A/CD159a, or (B) Human NKG2B/CD159b and eGFP was stained with Mouse Anti-Human NKG2A/CD159a Monoclonal Antibody (Catalog # MAB1059) followed by APC-conjugated anti-Mouse IgG secondary antibody (Catalog # F0101B). Quadrant markers were set based on control antibody staining (Catalog # MAB003). View our protocol for Staining Membrane-associated Proteins.Detection of NKG2A/CD159a by Flow Cytometry
Killer immunoglobulin-like receptor (KIR) expression is enriched in NKG2A- natural killer (NK) cells. (A) Day 12 expanded CD56bright NK cells were gated on NKG2A expression. (B) NKG2A+ (top) and NKG2A− (bottom) cells were interrogated for their expression of both KIR2DL1/DS1 and KIR3DL1/DS1 (left). KIR2DL2/DL3/DS2 expression was examined on the double positive cells (right). (C) Percent of total NKG2A+ or NKG2A− cells that are positive for all three KIRs. Statistical significance was assessed by Student’s t-test. (D) Day 0 CD56dim NK cells were gated on NKG2A expression. (E) NKG2A+ (top) and NKG2A− (bottom) cells were interrogated for their expression of both KIR2DL1/DS1 and KIR3DL1/DS1 (left). KIR2DL2/DL3/DS2 expression was examined on the double positive cells (right). (F) Percent of total NKG2A+ or NKG2A− cells that are positive for all three KIRs. Statistical significance was assessed by Student’s t-test (*p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001).
