    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.

  • 蛋白標(biāo)簽：
    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.
  • 產(chǎn)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.
  • 復(fù)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.
  • 儲(chǔ)存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質(zhì)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.
  • 貨期：
    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.
  • 注意事項(xiàng)：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet ：

靶點(diǎn)詳情

  • 功能：
    One of the proteins required for the normal export of some preproteins out of the cell cytoplasm. It is a molecular chaperone that binds to a subset of precursor proteins, maintaining them in a translocation-competent state. For 2 proteins (MBP, MalE and PhoA) the substrate is wrapped around the homotetramer, which prevents it from folding. It also specifically binds to its receptor SecA. Its substrates include DegP, FhuA, FkpA, GBP, LamB, MalE (MBP), OmpA, OmpF, OmpT, OmpX, OppA, PhoE, TolB, TolC, YbgF, YcgK, YgiW and YncE.

    1. the primary role of SecB is to facilitate the targeting of secretory proteins to the Sec-translocase PMID: 16352602
    2. SecB residues involved in contacts with the unfolded form of bound precursor, galactose-binding protein, are identified as those that upon addition of the unfolded polypeptide ligand show changes in spectral line shape. PMID: 16962134
    3. effect of chaperone SecB on folding & unfolding pathways of maltose binding protein at the single-molecule level; interactions with SecB prevent stable tertiary contacts in core structure but have no detectable effect on folding of external alpha helices PMID: 18048690
    4. SecB exhibits the remarkable ability to bind a diverse group of ligands recognizing them by virtue of the fact that they have non-native structure. PMID: 19569227
