GITR Protein, Mouse (HEK293, His)
Based on 1 Customer Validation
GITR (TNFRSF18) is a member of the TNFR superfamily. GITR promotes T cell activation and proliferation and increases resistance to tumors and viral infections, and exacerbates autoimmune diseases and inflammation processes. GITR Protein, Mouse (HEK293, His) is a recombinant protein with a C-terminal His label and is produced in HEK293 cells.
- Species: Mouse
- Source: HEK293

Biological Activity
GITR (TNFRSF18) is a member of the TNFR superfamily. GITR promotes T cell activation and proliferation and increases resistance to tumors and viral infections, and exacerbates autoimmune diseases and inflammation processes[1]. GITR Protein, Mouse (HEK293, His) is a recombinant protein with a C-terminal His label and is produced in HEK293 cells.
GITR is expressed on regulatory T cells (Tregs) and some activated immune cells, including effector T lymphocytes, nature killer (NK) cells, and neutrophils[1].
The amino acid sequence of human GITR protein has low homology for mouse GITR protein.
GITR does not have any enzymatic activity and signaling is propagated via recruiting TRAF-family members, specifically TRAF1, TRAF2 and TRAF5, to the GITR-signaling complex. The signaling is then mediated through NF-kB and MAPK pathways. GITR does not have any enzymatic activity and signaling is propagated via recruiting TRAF-family members, specifically TRAF1, TRAF2 and TRAF5, to the GITR-signaling complex. The signaling is then mediated through NF-kB and MAPK pathways, protecting T cells from TCR activation-induced cell death[2].
GITR (Glucocorticoid-induced TNFR-related protein, also known as TNFRSF18) is a type I transmembrane protein. GITR stimulates the proliferation of effector T-lymphocytes and partially reverses the immunosuppressive function of CD4+CD25+ Tregs[1]. GITR is activated by its ligand GITRL (TNFSF18). GITR induces NOS in murine macrophage in a time and dose-dependent manner[3]. GITR inhibits Multiple Myeloma (MM) cell proliferation in vitro and in vivo and induces apoptosis[4].
GITR (mouse; .1, .1, .2, .5 µg/mL; -46 h) increases the generation of nitric oxide in a dose and time-dependent manner in mouse macrophage RAW 264.7 cells[3].
GITR overexpressing cells are injected into SCID-bg mice via tail, showing a significant reduction of growth of MM cells in mice after 4 weeks in bone marrow tissues[4].
Measured by its binding ability in a functional ELISA. Immobilized Mouse GITR at 2 μg/mL (100 μL/well) can bind Biotinylated Human GITR Ligand. The ED50 for this effect is 16.44 ng/mL.

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
