FC - Quality tested

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Description:

GITR (glucocorticoid-induced TNFR-related gene) is a member of the TNF receptor superfamily, also known as TNFRSF18 and AITR (in humans). It is expressed at low levels on resting T lymphocytes and at high levels on CD25+ CD4+ Tregs. The expression of GITR on T cells can be upregulated upon activation. Interaction of GITR with its ligand (GITRL) has been demonstrated to augment T cell activation, proliferation, cytokine production as well as MAPKs and NF-κB activation, and abrogate the inhibitory function of CD25+ CD4+ Tregs. In vivo activation of GITR causes development of autoimmune diseases and restores the suppressed immune response.

Other Names: Glucocorticoid-induced TNFR -related gene, TNFRSF18
Structure: 66-70 kD homodimer of TNFR superfamily member.
Distribution: Low levels on resting T cells, B cells, and macrophages; high levels on CD25+ CD4+ Tregs and CD25+ CD4+ CD8- thymocytes.
Function: Stimulation of GITR can abrogate or reduce the inhibitory function of CD25+ CD4+ Treg cells. In vivo activation of GITR may lead to the development of autoimmune diseases.
Ligand Receptor: GITR ligand (GITRL).
Regulation: Activation of T and B cells can upregulate GITR expression.
