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
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

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. Activates the MAPK signaling pathway and induces cell migration.
Gene References into Functions
  1. A decrease of IGFBP6 expression can involve a decrease in the expression of N-cadherin and transcription factor Slug. PMID: 29577195
  2. IGFBP-6 could inhibit invasion and migration of colorectal carcinoma cells PMID: 29439316
  3. IGFBP6 might be an important regulator and prognostic factor for glioma. PMID: 27650075
  4. Results suggest that insulin like growth factor binding protein 6 (IGFBP6) may be an independent prognostic biomarker for nasopharyngeal carcinoma (NPC). PMID: 27623076
  5. We identified a novel SNP variant, Chr12:g.53494591T>C. c.T430C (p.S144P) in the insulin-like growth factor binding protein-6 (IGFBP6) gene. This variant was shared by all affected family members, but not by unaffected members. The c.T430C (p.S144P) variant of IGFBP6 was identified as the likely causal variant associated with increased risk of familial disc degeneration in the studied pedigree. PMID: 28829625
  6. We found that IGFBP6 and SATB2 were significantly down-regulated in HIV-infected CEM*174 cells and 3 different cohorts of HIV/AIDS patients while their promoters were predominantly hyper-methylated compared with normal controls. PMID: 26039376
  7. IGFBP6 attenuation in ACTH-secreting pituitary adenomas is associated with tumor growth, through activation of PI3K-AKT-mTOR pathway PMID: 24379119
  8. CCL-18 and IGFBP-6 were identified as new potential serum biomarkers for prostate cancer. PMID: 24747338
  9. When the concentrations of IGFBP-6 or KNG1 were greater than 98.5 pg/ml or 88.5 ng/ml, respectively, they predicted the proliferative vitreoretinopathy prognosis. PMID: 23808406
  10. Data indicate that IGFBP-6 binds to prohibitin-2 on the cell membrane, and knockdown of the latter abrogates IGFBP-6-induced migration. PMID: 24003225
  11. Review of the IGF system in physiology and disease with a focus on the regulation and actions of IGFBP-6, and its potential roles in cancer cells. PMID: 23126425
  12. These results suggest that the expression of IGFBP-6 in vascular endothelial cells is up-regulated by hypoxia and IGFBP-6 inhibits angiogenesis in vitro and in vivo PMID: 21618524

  14. TCDD at low concentrations may have a negative effect on cell apoptosis and down-regulate gene expression of IGFBP-6 in SaOS-2 cells. PMID: 18724896
  15. Hh pathway is aberrant activation in colorectal carcinoma cell line. Its inhibitor may be effectual agent for colorectal cancer chemoprevention. Gli1 maintained cell survival by binding promoter regions and facilitating transcription of IGFBP6 and Bcl-2. PMID: 21940310
  16. When IGFBP-6 gene expression was downregulated, cell proliferation was inhibited and apoptotic cell death was increased. PMID: 21820463
