    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.

    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 Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
    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：
    Gating-modifier toxin that targets voltage-gated sodium channels with a selective activity on Nav1.7/SCN9A (IC(50)=1-1.5 nM). It inhibits both activation and inactivation. For inhibition of activation, it is 100-fold more selective for Nav1.7/SCN9A (IC(50)=0.26-3) than for other sodium channels (Nav1.2/SCN2A (IC(50)=40-540 nM), Nav1.3/SCN3A (IC(50)=102 nM), Nav1.4/SCN4A (IC(50)=30-39 nM), Nav1.5/SCN5A (IC(50)=19-90 nM), Nav1.6/SCN8A (IC(50)=26 nM), and Nav1.8/SCN10A (IC(50)=146 nM)). For inhibition of inactivation, it is 20-fold more potent in inhibiting inactivation on Nav1.7/SCN9A (IC(50)=250 nM) than other channels (about 4.6 uM for all channels). It also weakly inhibits Cav1.2/CACNA1C and Cav3.2/CACNA1H (29% block at 1 uM). It inhibits Nav1.7/SCN9A activation by interacting with DII and impairs Nav1.7/SCN9A inactivation by interacting with DIV. It docks on top of the DII S3 helix Nav1.7/SCN9A. It is about 60-fold less active on Nav1.7/SCN9A at depolarized potential (0 mV; IC(50)=15 nM), compared to -120 mV potential (IC(50)=0.26 nM). This toxin binds to lipid membrane. This ability correlates with hNav1.7/SCN9A inhibition, showing that membrane binding is the first step in the inhibitory mechanism of this toxin. It inhibits Nav1.2/SCN2A less potently when it is coexpressed with SCN2B or SCN4B than when it is expressed alone, showing that beta subunits (SCN2B and SCN4B) have a protective effect.
  • 亞細(xì)胞定位：
    Secreted.
  • 蛋白家族：
    Phrixotoxin family
  • 組織特異性：
    Expressed by the venom gland.
