    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°C/-80°C. 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:
    3-7 business days
  • 注意事項(xiàng):
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet & COA:

靶點(diǎn)詳情

  • 功能:
    DNA helicase that stimulates viral DNA replication and recombination. Plays a role in T4 DNA replication initiation by selecting and activating DNA origins. Acts by dissociating and reassociating with the DNA molecule being unwound. Unwinds DNA as a monomer in a 5'-to-3' direction at a rate of 250 bp/s and can efficiently displace proteins from the DNA.
  • 基因功能參考文獻(xiàn):
    1. Gp32 plays both positive and negative roles in regulating Dda helicase activity, and that both effects may influence the outcome of complex DNA transactions such as replication fork restart. PMID: 25481875
    2. Dda cross-links to DNA in the 167-199 Peptide. PMID: 19256528
    3. Dda suffice to rescue stalled T4 replication forks in vitro PMID: 15194689
    4. Enhanced binding to the longer single-stranded overhangs was not responsible for enhanced processivity under conditions of excess Dda enzyme. Rather, multiple molecules of Dda bound to the same substrate exhibit greater processivity for DNA unwinding. PMID: 16185067
    5. observations demonstrate a complex mechanism containing nonuniform steps for a monomeric helicase PMID: 16474403
    6. Multiple Dda molecules act to displace DNA binding proteins in a manner that correlates with the DNA unwinding activity and streptavidin displacement activity. PMID: 16738140
