    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.

  • 蛋白标签：
    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.
  • 产品提供形式：
    Lyophilized powder

  • 复溶：
    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.
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保质期：
    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.
  • 货期：
    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.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

    5. Pediatric CNS-PNETs evade immune recognition by downregulating cell surface MHC-I and CD1d expression. Intriguingly, expression of SERPINB9, SERPINB1, and SERPINB4 is acquired during tumorigenesis in 29%, 29%, and 57% of the tumors PMID: 26963506
    6. It is a promising serological marker for hepatocellular carcinoma. PMID: 24635038
    7. our findings established that SCCA1 contributes to tumorigenesis by promoting EMT and a UPR-dependent induction of NF-kappaB and IL6 autocrine signaling that promotes a protumorigenic inflammation. PMID: 25213322

    14. Results indicate that cellular overexpression of SERPINB4 inhibits recombinant GrM-induced as well as NK cell-mediated cell death. PMID: 21857942
    15. Data suggest that SCCA1 inhibits cell death induced by lysosomal injury while, on the other hand, it sensitizes cells to ER stress by activating caspase-8 independently of the death receptor apoptotic pathway. PMID: 21576355
    16. Elevated serum SCCA1 is associated with squamous cell carcinoma in cervical cancer. PMID: 21338226
    17. Transgenic mice expressing human SCCA1 showed higher liver regenerative potential compared to wild-type mice, supporting the dual role of this serpin as an anti-apoptotic and pro-proliferative stimulus for liver cells in vivo. PMID: 19956912

    21. SCCA variants are overexpressed in hepatocellular carcinoma independently of tumour etiology PMID: 14970861
    22. SCCAs can alter invasive phenotype of cervical squamous cell carcinoma cells, probably by stimulating proMMP-9 production, and intact conformational structure of SCCAs is required for its stimulatory activity on proMMP-9 production PMID: 16211231
    23. Up-regulation of squamous cell carcinoma antigen-1 (SCCA1) suppresses c-Jun NH2-terminal kinase-1 (JNK1) and thus blocks UV-induced keratinocyte apoptosis. PMID: 16549498
    24. These results, in transgenic mice, suggest that SCAA1 might serve as an hepatitis B virus receptor or co-receptor and play an important role in mediating HBV entry into hepatocytes. PMID: 16820864
    25. SCCA2 regulates cell migration and invasion via E-cadherin expression, suggesting that SCCA2 may be involved in cancer behavior such as invasion or metastasis. PMID: 17016656
