Product Specific Information

The DTA-1 monoclonal antibody reacts with mouse GITR (Glucocorticoid-Induced TNFR family gene, also known as TNFRSF18).
In naive mice, GITR is expressed predominantly by CD4⁺CD25⁺ T regulatory cells (Treg) and by CD25⁺ CD4⁺ CD8⁻ thymocytes.
Stimulation of GITR with DTA-1 antibody abrogates Treg cell-mediated suppression. Although it does not deplete CD357 expressing cells in vivo, it has been shown to induce tumorogenesis. The removal of GITR-expressing Treg cells or the administration of DTA-1 resulted in organ-specific autoimmune disease.

Applications Reported:
This DTA-1 antibody has been reported for use in flow cytometric analysis.

Applications Tested:
Tested by flow cytometric analysis of mouse splenocytes. Recommended ≤0.06 µg per test (in 100 µL volume). Cell number may range from 10⁵–10⁸ cells/test. Antibody titration is recommended for optimal performance.

Fluorophore Information:
eFluor® 450 is an alternative to Pacific Blue®.

• Excitation: 405 nm
• Emission: 445 nm

  Filtration: 0.2 µm post-manufacturing filtered.

Target Information

Tumor necrosis factor receptor superfamily member 18 (TNFRSF18), also called GITR or AITR, is encoded by the TNFRSF18 gene located at 1p36.33.
This receptor is upregulated upon T-cell activation and plays a key role in maintaining immunological self-tolerance via CD25⁺CD4⁺ regulatory T cells.
Knockout studies in mice suggest its involvement in CD3-driven T-cell activation and apoptosis regulation.
Three alternatively spliced transcript variants encoding distinct isoforms have been reported.
