CD94 antibodies, human

CD94 antibodies, human

Clone: REA113 | Dilution: 1:50
The clone REA113 recognizes CD94, an approximately 45 kDa, single-pass type II transmembrane protein, which belongs to the C-type lectin superfamily. CD94 associates covalently with NKG2 family members and forms disulfide bonded heterodimers. CD94-NKG2 receptors bind HLA-E, the non-classical MHC class Ib molecule. Depending on the associated NKG2 member, CD94-NKG2 heterodimer transmits either activating or inhibitory signal. For, e.g, via immunoreceptor tyrosine based-inhibitory motifs (ITIMs) containing NKG2A, CD94-NKG2A heterodimers inhibit NK cell cytotoxicity. Besides NK cells, expression of CD94-NKG2 heterodimers is also shown on NK-T cells and a small percentage of CD8 cells in mice, where the crosslinking of CD94-NKG2 was shown to reduce the level of spontaneous apoptosis.
Additional information: Clone REA113 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.
