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.
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
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Urea channel that facilitates transmembrane urea transport down a concentration gradient. A constriction of the transmembrane channel functions as selectivity filter through which urea is expected to pass in dehydrated form. The rate of urea conduction is increased by hypotonic stress. Plays an important role in the kidney medulla collecting ducts, where it allows rapid equilibration between the lumen of the collecting ducts and the interstitium, and thereby prevents water loss driven by the high concentration of urea in the urine. Facilitates urea transport across erythrocyte membranes. May also play a role in transmembrane water transport, possibly by indirect means.
Gene References into Functions
  1. functional deficiency of all UTs caused a urea-selective urine-concentrating defect with little physiological abnormality in extrarenal organs. PMID: 27914708
  2. We conclude that transgenic expression of UT-A1 restores basal urea permeability to the level in wild-type mice but does not restore vasopressin-stimulated levels of urea permeability. This information suggests that transgenic expression of UT-A1 alone in mice lacking UT-A1 and UT-A3 is sufficient to restore urine-concentrating ability PMID: 26407594
  3. These results demonstrate that the descending thin limb (DTL) of the intermediate loop is composed of type I epithelium and expresses both UT-A2. The functional role of the DTL of the intermediate loop may be distinct from the short or long loops. PMID: 27091563
  4. Studies indicate that expression of urea transporter UT-B confers high urea permeability to erythrocytes. PMID: 25298342
  5. Studies indicate that urea transporter Slc14a1 UT-B is an indispensable transporter involved in maintaining physiological functions in different tissues. PMID: 25298344
  6. Data suggest that urea transporter UT-B may play an important role in protecting bladder urothelium by balancing intracellular urea concentration. PMID: 24204711
  7. Thienoquinoline PU-14 is a selective UT inhibitor and has urea-selective diuretic activity. PMID: 23486518
  8. AQP9 and unidentified UT-A urea channels constitute primary but redundant urea facilitators in murine hepatocytes PMID: 23042941
  9. Urea transporter-B-null mice showed defective urine concentrating ability. PMID: 22289137
  10. UT-B null mice exhibited depression-like behavior, with urea accumulation, nitric oxide reduction, and selective neuronal nitric oxide synthase level increase in hippocampus. PMID: 21750947
  11. UT-A2 deletion in UT-B knockout mice partially remedies the urine concentrating defect caused by UT-B deletion. PMID: 21849488
  12. UT-B has a role in urinary concentrating ability in mice PMID: 12133842
  13. potassium depletion is associated with reduced expression of UT-A1, UT-A3, and UT-B but increased expression of UT-A2 PMID: 12952854
  14. UT-B-deficient mice reveal that countercurrent exchange of urea in renal medullary vessels and red blood cells accounts for a major part of the kidney's concentrating ability and for the adaptation of renal urea handling during a high-protein intake. PMID: 12965892
  15. UT-B null mice have a normal glomerular filtration rate but moderately reduced urea clearance PMID: 15821253
  16. This review focuses on the erythrocyte urea transporter UT-B. PMID: 17264984
  17. UT-B plays an important role in eliminating urea produced by Sertoli cells and UT-B deletion causes both urea accumulation in the testis and early maturation of the male reproductive system. PMID: 17475664
  18. Data indicate that UT-B deletion caused the dynamic expression regulation of TNNT2 and ANP, and these proteins may provide new clues to investigate the molecular events involved in cardiac conduction. PMID: 19132680
  19. Results provide the first evidence that UT-B deletion causes progressive heart block in mice. PMID: 19471871
