Description

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, Fc-His) is a recombinant protein with a C-terminal Fc label and a C-terminal His label, It consists of 132 amino acids (S22-H153) and is produced in HEK293 cells.

Background

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].

In Vitro

GITR (mouse; 0.01, 0.1, 0.2, 0.5 µg/mL; 0-46 h) increases the generation of nitric oxide in a dose and time-dependent manner in mouse macrophage RAW 264.7 cells[3].

In Vivo

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
