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.

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.

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

IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Also exhibits IGF-independent antiproliferative and apoptotic effects mediated by its receptor TMEM219/IGFBP-3R. Promotes testicular germ cell apoptosis.

  1. Compound 49b treatment inhibited these retinal changes. In REC cultured in hypoxia, levels of IGFBP-3 were reduced, which were significantly increased by Compound 49b. PMID: 27439004
  2. Study indicated that IGFBP-3 shRNA might rehabilitate erectile function via decreased concentrations of serum LDL lipoprotein and triglyceride, increased cavernosal smooth muscle and improvement in NO-cGMP signaling in diabetic rats. PMID: 25879169
  3. IGFBP-3 shRNA may rehabilitate erectile function via increases of concentrations of serum testosterone and cavernous cyclic guanosine monophosphate in streptozotocin-induced diabetic rats PMID: 25582342
  4. IGFBP-3 has novel protective effects on retinal and systemic vasculature and may be a therapeutic candidate for ocular complications such as diabetic retinopathy. PMID: 22792172
  5. obesity induces specific changes in the expression profile of the adipose tissue depot surrounding the pancreas, leading to a decrease in IGFBP3 secretion PMID: 22067319
  6. The results support the suggestion that inactivation of Mxi1 has a positive effect on cell proliferation by down-regulating IGFBP-3. PMID: 22008548
  7. Paraquat-treated rats showed enhanced gene expression of growth factors such as platelet-derived growth factor-A and insulin-like growth factor-1 at 21 days and transforming growth factor-beta 1 at 14 days. PMID: 20498031
  8. Data suggest that the inhibitory effect of chronic arthritis on skeletal muscle is higher in fast glycolytic than in slow oxidative muscle and that IGF-I administration attenuates this effect and decreases atrogin-1 and IGFBP-3 gene expression. PMID: 20519361
  9. Downregulation of IGFBP-3 gene expression may cause pulmonary hypoplasia in the nitrofen-induced CDH model by interfering with retinoid signaling pathway. PMID: 19844724

  11. IGFBP-3 and -5 proteins may have potential modulatory roles in type I fiber-dominated muscles, aging, and regrowth from atrophy. PMID: 12397024
  12. role of glucocorticoids in the insulin-like growth factor binding protein (IGFBP)-3 response to endotoxin PMID: 12485840
  13. Expressed in cardiac muscle cells. Serum withdrqwal-induced increase in apoptosis of cardiac muscle cells associated with IGFBP-3. PMID: 12508914
  14. data indicate that acute inflammation inhibits serum concentrations of IGFBP-3 by decreasing its synthesis in the liver, rather than increasing its proteolysis PMID: 12581876
  15. Aminoguanidine inhibition of inducible nitric oxide synthase blocked the inhibitory effect of LPS on both IGFBP-3 serum levels and its hepatic mRNA levels. PMID: 13129855
  16. IGFBP-3 could play proapoptotic action at the myocardial level and suggest a novel role for this protein in cardiovascular dysfunction. PMID: 15055478
  17. IGF-I uses different and only partially overlapping intracellular signaling pathways for regulation of IGFBP-3 and -5 with opposing biological functions might be important for modulation of IGF bioactivity in cellular microenvironment. PMID: 15845624
  18. cross-talk between the IGFBP-3-dependent STAT-1 signaling and the TGF-beta-dependent ERK pathway that regulates mesenchymal chondroprogenitor cell proliferation PMID: 15956343
