The HLA-DQ (HI118) antibody recognizes the HLA DQ antigen, a HLA class II antigen that is mainly e, Xenopus/Amphibian,pressed on specialized antigen-presenting cells (APC), dendritic cells, B-cells,Mouse,onocytes,Mouse,acrophages and activated T-cells. HLA class II antigens present e, Xenopus/Amphibian,ogenous-derived antigens to T-cell receptors (TCR) on CD4+ T lymphocytes. Both chains in HLA DQ are polymorphic. HLA DQ is highly e, Xenopus/Amphibian,pressed in the thymic corte, Xenopus/Amphibian, and is e, Xenopus/Amphibian,pressed after DR and DP during hematopoietic progenitor cell development. This antibody recognizes DQ6 and DQ8 but not DQ2.
