CD159a (NKG2A) antibodies, human

CD159a (NKG2A) antibodies, human

Clone: REA110 | Dilution: 1:50
Clone REA110 recognizes CD159a, an inhibitory natural killer (NK) cell receptor. CD159a forms heterodimer with CD94 and contains a C-type lectin ectodomain. Inhibitory signal is transmitted by the heterodimer via immunoreceptor tyrosine-based inhibitory motifs (ITIMs) and upon ligand engagement, ITIMs are phosphorylated and transmit signal through docking of various tyrosine phosphatases. CD159a/CD94 binds non-classical MHC class I protein, HLA-E. Expression of CD159a is found mainly on NK cells and on subsets of CD8
Additional information: Clone REA110 displays negligible binding to Fc receptors.

REAfinity clone is tested against different known clones, in a blocking experiment, to identify whether they recognize completely overlapping (++), partially overlapping (+), or completely different epitopes (-). In a blocking experiment, cells are incubated with an excess of purified unconjugated REAfinity clone followed by staining with conjugated form of the other known clones.
