Rat Anti- Mouse CD94- UNLB(0.5 mg)

The monoclonal antibody 18D3 reacts with the mouse CD94 receptor subunit, a 70kDa type II transmembrane glycoprotein. CD94 is expressed on the surface of NK cells, NK T cells and some memory phenotype CD8⁺ cells.2 When CD94 is paired with NKG2A, C, or E subunit, it binds the nonclassical MHC class Ib molecule Qa-1b and results in a CD94high population by flow cytometry.^{1, 2} Approximately half of NK cells do not express NKG2A, C or E; these cells express CD94 on the surface in a form that does not bind Qa-1b and is believed to be nonfunctional, producing a CD94low population by flow cytometry.^{1, 2} CD94 is thought to play a role in the adhesion and activation of the NK cell lineage.
