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.
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
Participates in the Wnt signaling pathway. Binds to DNA and acts as a repressor in the absence of CTNNB1, and as an activator in its presence. Necessary for the terminal differentiation of epidermal cells, the formation of keratohyalin granules and the development of the barrier function of the epidermis. Down-regulates NQO1, leading to increased mitomycin c resistance.
Gene References into Functions
  1. HIPK2 up-regulates transcription by phosphorylating TCF3, a transcriptional repressor, but inhibits transcription by phosphorylating LEF1, a transcriptional activator. PMID: 21285352
  2. Tcf3is partially responsible for the butyrate-resistant phenotype of colorectal cancer cells, as this DNA-binding protein suppresses the hyperinduction of Wnt activity by butyrate. PMID: 23063976
  3. Our results identify TCF3 as a central regulator of tumor growth and initiation. PMID: 23090119
  4. TCF3, a novel positive regulator of osteogenesis, plays a crucial role in miR-17 modulating the diverse effect of canonical Wnt signaling in different microenvironments. PMID: 23492770
  5. TCF/TLE tetramer complex promotes structural transitions of chromatin to mediate repression. PMID: 24596249
  6. These results indicate that a dynamic interplay of TCF transcription factors governs MYC gene expression in colorectal cancers. PMID: 25659031
  7. TCF7L1, a Wnt pathway repressor, buffers CTNNB1/TCF target gene expression to promote CRC growth PMID: 27333864
  8. TCF7L1 plays a major role in maintaining hESC pluripotency, which has implications for human development during gastrulation PMID: 29361574
  9. Through transcriptome profiling and combined gain- and loss-of-function studies, the authors identified LCN2 as a major downstream effector of TCF7L1 that drives tumor growth. PMID: 28467300
  10. report the identification of two independent missense variants in human TCF7L1, p.R92P and p.R400Q, in a cohort of patients with forebrain and/or pituitary defects PMID: 26764381
  11. No difference in nuclear beta-catenin signal intensity was found, which may be caused by an alteration in Wnt pathway in microsatellite stable sporadic tumors by unknown mechanisms leading to lower TCF-3, 4 protein expression. PMID: 20532534
