Form 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.
Buffer before Lyophilization Tris/PBS-based buffer, 6% Trehalose, pH 8.0
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.

Protein 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.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Gustducin-coupled receptor immplicated in the perception of bitter compounds in the oral cavity and the gastrointestinal tract. Signals through PLCB2 and the calcium-regulated cation channel TRPM5. Activated by the sulfonyl amide sweeteners saccharin and acesulfame K. In airway epithelial cells, binding of bitter compounds increases the intracellular calcium ion concentration and stimulates ciliary beat frequency. May act as chemosensory receptors in airway epithelial cells to detect and eliminate potential noxious agents from the airways.
Gene References into Functions
  1. those with at least one sensitive TAS2R38 allele (AP or PP genotype) were more likely to report rejecting liquid medications than were those without a taster allele (AA genotype PMID: 26391354
  2. Study demonstrates that the response profiles of the cat bitter receptors Tas2r38 and Tas2r43 are distinct from those of their orthologous human receptors PMID: 26037485
  3. The effect of the TAS2R43 gene on coffee liking is mediated by caffeine and in particular by the H212R variant. PMID: 24647340
  4. Studies indicate that bitter-tasting compounds can have specific physiological effects in Bitter-tasting compounds can have specific physiological effects in type 2 taste receptors (T2Rs)-expressing cells. PMID: 22964302
  5. The mutational polymorphism TAS2R43 significantly affects susceptibility to BEN points to a potentially broad role for toxin responses in personal health risks. PMID: 23050764
  6. Our results show that the expression rate of some of the T2R taste receptor genes was increased significantly in patients with phantogeusia. PMID: 22397221
  7. hTAS2R43 and hTAS2R44 function as cognate bitter taste receptors and do not contribute to the sweet taste of saccharin and acesulfame K. PMID: 15537898
  8. hT2R43 gene allele makes people more sensitive to the bitterness of an artificial sweetener, saccharin; in addition, a closely related gene's (hT2R44's) allele also makes people more sensitive to the bitterness of saccharin. PMID: 17702579
