    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 ：

靶点详情

  • 功能：
    Component of the zona pellucida, an extracellular matrix surrounding oocytes which mediates sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy. The zona pellucida is composed of 3 to 4 glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP4 may act as a sperm receptor.
  • 基因功能参考文献：
    1. ZO4 is highly expressed in ovarian tissue in PCOS patients with regular cycle and without hyperandrogenism; in some patients with PCOS and infertility, ZP4 mutation can be found. PMID: 25740067
    2. Human ZP4 is not sufficient to support human sperm binding to the zona pellucida in transgenic mice; other zona proteins may be needed for human gamete recognition. PMID: 21173071
    3. ZPB induces acrosomal exocytosis through a Gi independent pathway. PMID: 15805145
    4. Binding sites for recombinant zona pellucida B (ZPB) glycoprotein are located both at the N- and C-terminus of proacrosin PMID: 15950651
    5. Exposure of sperm to ZP proteins promoted acrosomal exocytosis and changed motility patterns. PMID: 16407501
    6. induces acrosome reactions which are protein kinase-C, protein tyrosine kinase, T-type Ca2+ channels, and extracellular Ca2+ dependent PMID: 18667750
    7. a significant decrease in acrosomal exocytosis mediated by both recombinant human ZP3 (p<0.005) and ZP4 (p<0.005) was observed in presence of the immune sera PMID: 19004505
