CD159a (NKG2A) antibodies, mouse

Clone: REA1161 | Dilution: 1:50
Clone REA1161 recognizes the CD159a (NKG2A) antigen, 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, NKT cells, and on subsets of CD8
Additional information: Clone REA1161 displays negligible binding to Fc receptors.
