    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：
    Odorant receptor which mediates acceptance or avoidance behavior, depending on its substrates. The odorant receptor repertoire encodes a large collection of odor stimuli that vary widely in identity, intensity, and duration. Involved in the behavioral responses ethyl butyrate and to esters in more general. Complexes with Orco to form odorant-sensing units, providing sensitive and prolonged odorant signaling and calcium permeability. They are necessary and sufficient to promote functional reconstitution of odor-evoked signaling in sensory neurons that normally respond only to carbon dioxide.
