CD94 Antibody [18d3]

The monoclonal antibody 18d3 reacts with the mouse CD94 receptor subunit, a type II transmembrane glycoprotein. CD94 is expressed on the surface of NK cells, NK T cells, and some memory phenotype CD8+ cells. 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. 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. CD94 is thought to play a role in the adhesion and activation of the NK cell lineage.
