Product Details

Description
Cytokine that binds to TNFRSF18/AITR/GITR. Regulates T-cell responses. Can function as costimulator and lower the threshold for T-cell activation and T-cell proliferation. Important for interactions between activated T-lymphocytes and endothelial cells. Mediates activation of NF-kappa-B. Triggers increased phosphorylation of STAT1 and up-regulates expression of VCAM1 and ICAM1 (PubMed:23892569). Promotes leukocyte adhesion to endothelial cells (PubMed:23892569). Regulates migration of monocytes from the splenic reservoir to sites of inflammation
Purity Greater than 94% as determined by SDS-PAGE.
Endotoxin Less than 1.0 EU/ug as determined by LAL method.

Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition Store at -20°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

  4. Serum GITRL levels were higher in SLE patients. PMID: 23251213
  5. Glucocorticoid-induced TNF-related ligand (GITRL) confers pseudoexpression to tumor cells by platelets, which results in GITRL expression by megakaryocytes and their platelet progeny. PMID: 22649191
  6. observation suggests a link between cytokine-regulated keratinocyte GITRL expression and its role in inflammatory responses in AD PMID: 22417213

  13. GITRL could be a potential candidate for regulation of the ocular immune privilege and the balance between immune privilege and inflammation PMID: 16874737
  14. Constitutive expression of GITRL by tumor cells diminishes natural killer cell antitumor immunity. PMID: 17360848
  15. although huGITRL is not capable of alleviating Treg suppression of responder T cells, huGITRL overexpression on monocyte-derived DC enhances their capacity to induce antigen-specific T cell responses PMID: 17449724
  16. These observations raise the possibility that the GITRL-mediated inflammatory activation of macrophages is involved in the pathogenesis of inflammatory diseases. PMID: 17602748
  17. Levels of AITRL were significantly increased in serum of breast cancer patients PMID: 17914571
