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
IRBP shuttles 11-cis and all trans retinoids between the retinol isomerase in the pigment epithelium and the visual pigments in the photoreceptor cells of the retina.
Gene References into Functions
  1. this report is the first to describe the retinal dystrophy in children caused by homozygous nonsense RBP3 mutations, highlighting the requirement for IRBP in normal eye development and visual function. PMID: 25766589
  2. CMPK1 and RBP3 are associated with corneal curvature in Asian populations. PMID: 24963161
  3. We found that most patients with macular telangiectasia-2 possess retinal autoantibodies, the most prevalent of which were directed against AGL, RBP3, and CK-B. PMID: 23882694
  4. Secretory defect and cytotoxicity: the potential disease mechanisms for the retinitis pigmentosa (RP)-associated interphotoreceptor retinoid-binding protein (IRBP). PMID: 23486466
  5. The mouse retina promotes cone dark adaptation eightfold faster than the retinal pigment epithelium. However, complete cone recovery requires both visual cycles. PMID: 21613504
  6. Underproduction of IRBP is an early event in the human diabetic retina and is associated with retinal neurodegeneration. PMID: 19823802
  7. studies suggest that IRBP and S-Ag can initiate innate and, in sensitive individuals, adaptive immune response by attracting iDCs and T and B cells expressing CXCR3 and CXCR5 PMID: 15713799
  8. analysis of IRBP proteolysis is useful as a biomarker for uveitis PMID: 18266969
  9. Mutations in RBP3 are an infrequent cause of autosomal recessive retinitis pigmentosa. PMID: 19074801
  10. In interphotoreceptor retinoid-binding protein transgenic mice cone dysfunction appears to be caused by abnormal trafficking of cone opsins due to impaired delivery of all-transretinaldehyde chromophore without IRBP. PMID: 19193895
