    Note: The complete sequence including tag sequence, target protein sequence and linker sequence could be provided upon request.
  • 蛋白標(biāo)簽：
    N-terminal 6xHis-tagged
  • 產(chǎn)品提供形式：
    Liquid or 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.
  • 緩沖液：
    If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
  • 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：
    3-7 business days
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

靶點詳情

  • 功能：
    Protective antigen constitutes one of the three proteins composing the anthrax toxin; it mediates attachment to host cells and translocation of edema factor (EF) and lethal factor (LF) into the host cytoplasm. PA associated with LF forms the lethal toxin (LeTx) and causes death when injected; PA associated with EF forms the edema toxin (EdTx) and produces edema. PA induces immunity to infection with anthrax.; Mediates the attachment to host cells by binding host cell receptors ANTXR1 and ANTXR2. Following host cell surface attachment, PA is cleaved by FURIN to generate the PA-63 (Protective antigen PA-63) form, which constitutes the mature form of the protein that oligomerizes and forms a pore to translocate the enzymatic toxin components edema factor (EF) and lethal factor (LF) into the host cytosol.; Mature form that oligomerizes and forms a pore to translocate the enzymatic toxin components edema factor (EF) and lethal factor (LF) into the host cytosol. Following attachment to host cell receptors and cleavage by FURIN, homooligomerizes to form ring-shaped oligomers that are in a pre-pore conformation, and associates with EF and LF. Toxin-leaded complexes are then endocytosed in a clathrin-dependent process, followed by a conformational change of oligomerized PA-63 from the pre-pore to pore state, which is triggered by the low pH in the endosome. Once active, the pore mediates unfolding of EF and LF, which pass through the pore and translocate into the host cytosol.
