Liquid or Lyophilized powder
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.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°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
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Receptor for the glycosphingolipid psychosine (PSY) and several related glycosphingolipids. Plays a role in immune response by maintaining lysosome function and supporting phagocytosis-mediated intracellular bacteria clearance. May have a role in activation-induced cell death or differentiation of T-cells.
Gene References into Functions
  1. TDAG8 functions as a contextual tumor suppressor down-regulated in hematological malignancies. PMID: 29017562
  2. Study results suggest greater T cell death associated gene-8 (TDAG8) expression in patients with panic disorder compared to healthy subjects, and directly link TDAG8 expression and the severity of the panic disorder symptoms PMID: 28736033
  3. this study establishes a role for GPR65 in inflammatory bowel disease susceptibility and identify lysosomal dysfunction as a potentially causative element in pathogenesis PMID: 27287411
  4. TDAG8 expression is decreased by more than 50%. PMID: 24152439
  5. GPR65 is a regulator upstream of MMP3, which is regulated by proton-sensing G-protein-coupled receptors PMID: 23707809
  6. Acidosis promotes Bcl-2 family-mediated evasion of apoptosis: involvement of acid-sensing G protein-coupled receptor Gpr65 signaling to Mek/Erk. PMID: 22685289
  7. Data suggest that one physiological function of TDAG8 is negative regulation of inflammation by inhibiting production of pro-inflammatory cytokines in T-lymphocytes and macrophages. PMID: 22445881
  8. These results support the hypothesis that TDAG8 enhances tumor development by promoting adaptation to the acidic environment to enhance cell survival/proliferation. PMID: 20855608
  9. GPR4 and TDAG8 overexpression in human tumors plays a role in driving or maintaining tumor formation PMID: 15221007
  10. TDAG8 is one of the proton-sensing GPCRs coupling to adenylyl cyclase and psychosine, and its related lysosphingolipids behave as if they were antagonists against protein-sensing receptors, including TDAG8, GPR4, and OGR1. PMID: 15326175
  11. TDAG8 may play biological roles in immune response and cellular transformation under conditions accompanying tissue acidosis. PMID: 15618224
  12. Expression of TDAG8 by immune cells may regulate responses in acidic microenvironments. PMID: 15665078
  13. At least partly, TDGA8 mediates extracellular acidification-induced inhibition of proinflammatory cytokine production through the Gs protein/cyclic AMP-dependent protein kinase A signaling pathway in transgenic mouse macrophages. PMID: 19234222
