Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
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.
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.
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

Function
Putative taste receptor. TAS1R1/TAS1R3 responds to the umami taste stimulus (the taste of monosodium glutamate). Sequence differences within and between species can significantly influence the selectivity and specificity of taste responses.
Gene References into Functions
  1. Genetic variants in TAS1R were associated with dietary consumption, which may be associated with gastric cancer risk PMID: 27321875
  2. The study provides human psychophysical evidence that TAS1R1 polymorphisms associate with modest differences in overall taste intensity, which were independent from other well-studied markers of variation in oral sensation. PMID: 24000232
  3. A complex molecular mechanism involving changes in the properties of both the orthosteric and non-orthosteric sites of T1R1 underlies the determination of ligand specificity in mammalian T1R1/T1R3. PMID: 24214976
  4. Data show that that Tas1r1 and Tas1r3 are expressed in murine and human spermatozoa. PMID: 22427794
  5. amino acid substitutions (A110V and R507Q) in the N-terminal ligand-binding domain of T1R1 severely impair receptor functions in vitro PMID: 21422378
  6. sequence differences in T1R receptors within and between species (human and mouse) can significantly influence the selectivity and specificity of taste responses PMID: 11894099
  7. findings demonstrate the different functional roles of T1R3 and T1R2 and the presence of multiple ligand binding sites on the sweet taste receptor PMID: 15353592
  8. In vivo taste bud signaling may proceed primarily through hT1R1 and hT1R2. PMID: 17506496
  9. human duodenal L cells express sweet taste receptor T1r. PMID: 17724330
  10. Taken together, these results suggest that Tas1R1-Tas1R3 receptor variants found in human fungiform papillae might contribute to inter-individual differences of sensitivity to L-glutamate. PMID: 19146926
  11. In our sample of subjects, the frequencies of 2 nsSNPs, C329T in tas1r1 and C2269T in tas1r3, were significantly higher in [glutamate] nontasters than expected, whereas G1114A in tas1r1 was more frequent in tasters. PMID: 19571223
