Anti-Mouse CD357 (DTA-1) ColorWheel^® Dye-Ready mAb

ColorWheelColorWheel^® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheelColorWheel^® antibody with any ColorWheelColorWheel^® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheelColorWheel^® antibody and dye is lyophilized for long-term storage, allowing for simplicity and flexibility without compromise. ColorWheelColorWheel^® technology requires both ColorWheelColorWheel^® antibody and ColorWheelColorWheel^® dye for Flow Cytometry application.

Tumor necrosis factor receptor superfamily member 18 (UniProt: O35714; also known as Glucocorticoid-induced TNFR-related protein, CD357) is encoded by the Tnfrsf18 (also known as Gitr) gene (Gene ID: 21936) in murine species. CD357 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-19), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 20-153), a transmembrane domain (aa 154-174), and a cytoplasmic domain (aa 175-228). The mature form also contains three TNFR-Cys repeats (aa 28-61; 62-101; 102-142). CD357 is expressed in lymph node and peripheral blood leukocytes and weakly in spleen. Its expression is up regulated in peripheral mononuclear cells after antigen stimulation/lymphocyte activation. It is preferentially expressed in activated T lymphocytes and serves as a receptor for TNFSF18 (hGITRL It is involved in interactions between activated T-lymphocytes and endothelial cells and in the regulation of T-cell receptor-mediated cell death. It is shown to be a crucial player in the differentiation and expansion of thymic Tregs (tTregs) and peripheral Tregs (pTregs). CD357 is suggested to be an attractive target for immunotherapy due to its capacity to promote effector T cell functions and hamper regulatory T cell suppression. (Ref.: Zappasodi, R., et al. (2019).

Clone DTA-1 is a rat monoclonal antibody that detects CD357 (GITR). It targets an epitope within the extracellular domain.

Lyophilized from PBS containing D-Mannitol and Sucrose, normal appearance is a dried pellet. Reconstituted antibody solution is stable and functional as assessed by functional testing. Contains no biocide or preservatives, such as azide.

1.0 mg/mL after reconstitution at 25 μL in PBS. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C. Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial. Reconstitute each vial by adding 25 μL PBS. Protect from light.
