    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
    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.
  • 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.
  • Datasheet ：

  • 功能：
    AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates. This subunit may act as an adapter protein that links AcrB and TolC stably together. It is elongated in shape, being long enough to span the periplasm.
  • 基因功能参考文献：
    1. The results underscore the importance of the periplasmic turn 1 of TolC in the functional assembly of the tripartite efflux complex and AcrA in transitioning TolC from its closed to open state. PMID: 20132445
    2. Our results indicate functional interactions between the AcrA -hairpin tip region and the TolC aperture tip region in the assembly of the functional tripartite efflux pump AcrAB-TolC. PMID: 20581201
    3. Data show that the AcrA-mediated suppression of mutant TolC phenotypes and stabilization of mutant TolC were dependent on AcrB, reflecting the existence of a functional complex between TolC and AcrAB in vivo. PMID: 15491355
    4. TolC-AcrA interaction demonstrated via cross-linking studies PMID: 15576805
    5. The observed pulsating behavior in inducible transcription of acrA is a systems property arising from the dependence of gene expression on multidrug resistance determinants. PMID: 16461398
    6. AcrS represses the gene expression of multidrug efflux genes, acrA and acrB PMID: 18567659
    7. Data suggest that recruitment of TolC by various MFPs AcrA, MacA, and EmrA is determined not only by kinetics of MFP-TolC interactions but also by oligomerization kinetics of MFPs and pH. PMID: 19805313
