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

Belongs to an adhesion system, probably together with the E-cadherin-catenin system, which plays a role in the organization of homotypic, interneuronal and heterotypic cell-cell adherens junctions (AJs). Nectin- and actin-filament-binding protein that connects nectin to the actin cytoskeleton. May play a key role in the organization of epithelial structures of the embryonic ectoderm. Essential for the organization of adherens junctions.
Gene References into Functions
  1. CLDN6 enhances the chemoresistance to ADM via activating the AF-6/ERK signaling pathway and up-regulating cancer stem cell characters in MDAMB231 cells. PMID: 29159771
  2. AF6 employs a non-canonical, evolutionarily conserved alpha-helix to bind RAS, unique to AF6 and the classical RASSF effectors. PMID: 29062045
  3. miR-188-3p is a novel independent prognostic factor in colorectal cancer patients, which can be partly explained by its effect on MLLT4 expression and migration of cancer cells. PMID: 27601590
  4. Afadin (AFDN), a cytoskeletal and junction-associated protein, was present in 2D and 3D keratinocyte cultures, and validated as a so-far-unknown EphA2-interacting protein. PMID: 27815408
  5. In pancreatic cancer cells, AF6 is expressed at reduced levels, causing Dvl2 to be upregulated and available to bind and enhance FOXE1-induced trans-activation of Snail, which promotes proliferation and metastasis. PMID: 26013125
  6. AF-6/afadin could be a useful selection marker for fertility-sparing therapy for patients with atypical hyperplasia or grade 1 endometrioid adenocarcinoma with no myometrial invasion. PMID: 25879875
  7. JAM-A regulates epithelial permeability via association with ZO-2, afadin, and PDZ-GEF1 to activate Rap2c and control contraction of the apical cytoskeleton. PMID: 23885123
  8. The expression levels of CFTR and AF-6/afadin are significantly downregulated in human colon cancer tissues. PMID: 24373847
  9. AF-6 is a positive modulator of the PINK1/parkin pathway and is deficient in Parkinson's disease. PMID: 23393160
  10. The interaction between the PDZ domain of afadin (AF6_PDZ) and a series of polypeptides comprising the PDZ-binding motif, was studied. PMID: 20586101
  11. Results demonstrate a role for afadin in the regulation of vascular barrier function via coordination of adherens junction-tight junction and p120-catenin-ZO-1 interactions. PMID: 21732359
  12. the Necl-5-nectin, nectin-nectin, and nectin-afadin interactions cooperatively increase the clustering of the nectin-afadin complex at the cell-cell contact sites, promoting the formation of the nectin-based cell-cell adhesion. PMID: 21880730
  13. AF6/afadin is a marker of poor outcome in breast cancer, and its loss induces cell migration, invasiveness and tumor growth PMID: 21478912
  14. Results demonstrate a novel molecular mechanism by which Rap1 and afadin regulate the VEGF- and S1P-induced angiogenesis. PMID: 20413783
  15. RYK, a catalytically inactive receptor tyrosine kinase, associates with EphB2 and EphB3 but does not interact with AF-6. PMID: 11956217
  16. Bcr kinase downregulates Ras signaling by phosphorylating AF-6 and binding to its PDZ domain PMID: 12808105
  17. Results report the solution structure of AF-6 PDZ domain and its interaction with the C-terminal peptides from Neurexin and Bcr. PMID: 15684424
  18. AF6 negatively regulates Rap1-induced cell adhesion. PMID: 16051602
  19. Loss of afadin is associated with breast cancer PMID: 16819513
  20. AF6/s-afadin is a candidate for mediating control of cellular growth processes by regulated translocation to the nucleus. PMID: 17013812
  21. c-Src is recruited by AF-6 to cell-cell contact sites, suggesting that c-Src is regulated by a PDZ protein in special cellular locations. PMID: 17491594
  22. AF6 protein is important for spreading of Herpes simplex virus 1 in epithelial cells PMID: 17967423
  23. two distal surfaces of the AF-6 PDZ domain respond differently to peptide binding; distal surface 1 changes in millisecond dynamics, whereas distal surface 2 undergoes structural rearrangement PMID: 18052198
  24. This paper deals with AF-6 in mouse, rat, and cow. PMID: 9722616
