Qa-1(b) Mouse anti-Mouse, Biotin, Clone: 6A8.6F10.1A6, BD

Mouse Monoclonal Antibody

Supplier:  BD Biosciences 559829

Catalog No. BDB559829

Description

The 6A8.6F10.1A6 monoclonal antibody reacts with the Qa-1(b) alloantigen, which is a nonclassical MHC class I (Class Ib) molecule encoded by the T23 gene of the H-2 complex. Qa-1 associates with β2-microglobulin and is expressed at low levels on most leukocytes and many other cell types. Its level of cell-surface expression is upregulated by IFNγ or specific peptides. Qa-1 is an oligomorphic molecule which presents a limited pool of peptides to T lymphocytes bearing α&β and γδTCR and binds to a large subpopulation of NK cells. In fact, Qa-1(b) is the ligand for CD94/NKG2A, CD94/NKG2C, and CD94/NKG2E receptors, which are expressed on NK cells. Furthermore, it has been reported that Qa-1 expressed on activated B lymphocytes is involved in immunoregulation by inducing T-cell-mediated suppression of antibody responses. The 6A8.6F10.1A6 mAb can detect Qa-1(b) on activated splenocytes from C57BL/6 and BALB/c mice (both Qa-1(b)), but not from A/j mice (Qa-1(a)), and it can block target cell recognition by CTLs specific for Qa-1-presented antigen.
