Anti-Human V beta 8 TCR eFluor® 450

Description: This JR-2 monoclonal antibody reacts with the human T cell receptor (TCR) Vβ 8 allele. Composed of an α and β chain, TCR specificity is typically determined by Vα, Jα, Vβ, Dβ, and Jβ gene rearrangement. Vß expression in humans has been examined in studies on the effects of superantigens, inflammation, autoimmune disease, and HIV infection. More recently, assessment of TCR Vβ expression has been used to phenotype T cell clonality in CD3+/TCRαβ+ large granular lymphocyte leukemias. A member of the Ig superfamily, this receptor is expressed on a subset of peripheral blood T cells.
