    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：
    Lanthionine-containing peptide antibiotic (lantibiotic) active on Gram-positive bacteria. The bactericidal activity of lantibiotics is based on depolarization of energized bacterial cytoplasmic membranes, initiated by the formation of aqueous transmembrane pores. When present individually, LchA2 exhibits activity towards B.subtilis L1 (IC(50)=30 uM), Rhodococcus sp. SS2 (IC(50)=16.6 uM), M.luteus B1314 (IC(50)=2.6 uM), B.megaterium VKM41 (IC(50)=2 uM), S.aureus 209p (IC(50)=20 uM), B.pumilus 2001, B.globigii I, B.amyloliquefaciens I, M.smegmatis 1171 and M.phlei 1291. However, when combined with LchA1, it displays much stronger activity against B.subtilis L1 (IC(50)=0.64 uM), Rhodococcus sp. SS2 (IC(50)=0.64 uM), M.luteus B1314 (IC(50)=0.09 uM), B.megaterium VKM41 (IC(50)=0.12 uM) and S.aureus 209p (IC(50)=0.64 uM). The activity of the combined LchA1 and LchA2 peptides is strongest at a molar ratio of 1. Even when applied at 17-fold concentration of the highest IC(50) values for Gram-positive bacteria, neither the individual nor the combined peptides display activity against Gram-negative bacteria P.aeruginosa PAO1, P.putida I-97 or E.coli C600.
