Human CD1d Tetramer (α-GalCer loaded)-PE

50 tests



The α3 mutation significantly reduces the binding of MHC tetramer to human CD8. To minimizes the aberrant effect of some CD8 antibodies; clone SFCI21Thy2D3 (also known as “T8”) is recommended.

Description/BackgroundNatural Killer T (NKT) cells, a type of T cell that plays a significant role in immune response, produces a large quantity of INF-gamma and IL-4 in response to glycolipids that presented by CD1d molecules. In recent years, NKT cells are reported to play a part in diabetes and tumor immunity. Therefore, a technology allowing quantitative measurement of CD1d-positive NKT cells would be a useful tool for immunology and clinical laboratory examinations. The development of MHC Tetramer technology has provided a breakthrough in the ability to follow T cell populations defined by their antigen specificity. Tetramers have been used widely to obtain a detailed analysis of the distribution and frequency of conventional CD4+ and CD8+ antigen-specific T cells during a variety of immune responses. T-Select Human CD1d Tetramer is a reagent created by tetramerizing biotinylated human CD1d/beta2m complexes with phycobiliprotein-labeled streptavidin. alpha-galactosylceramide (alpha-GalCer), a glycosphingolipid originally isolated from marine sponges, appears to be presented by CD1d to activate both human and mouse NKT cells. T-Select Human CD1d Tetramer (alpha-GalCer loaded) is a highly specific reagent for detection of NKT cells. Measurement can be performed using isolated lymphocytes/monocytes.
