  • 蛋白标签：
    N-terminal 10xHis-tagged
  • 产品提供形式：
    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.
  • 缓冲液：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
  • 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：
    Basically, we can dispatch the products out in 1-3 working days after receiving your orders. 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.

  • 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. ZP2 may act as a secondary sperm receptor.
  • 基因功能参考文献：
    1. The central peptide of ZP2 (190-505) is immunogenic and contains zona pellucida-specific epitopes. PMID: 27193969
    2. ZP2(51-149) sperm-binding domain is necessary for mouse gamete recognition and penetration through the zona pellucida. PMID: 24934154
    3. Studies indicate that eggs from mZP2-/- and mZP3-/- females lack a zona pellucida (ZP), and the mice are completely infertile due to a severely reduced number of ovulated eggs in their oviducts. PMID: 23417405
    4. Sperm arylsulfatase A binds to mZP2 and mZP3 glycoproteins in a nonenzymatic manner. PMID: 22685254
    5. Recombinant ovastacin cleaved ZP2 in native zonae pellucidae, documenting that ZP2 was a direct substrate of this metalloendoprotease. PMID: 22472438
    6. Cytoplasmic tails are necessary to prevent intracellular oligomerization while ensuring incorporation of processed ZP2 and ZP3 into the zona pellucida. PMID: 21378311
    7. The granulosa cells contribute more to the mZP2 mRNA synthesis than oocyte does. PMID: 20979237
    8. data indicate that sperm-egg recognition depends on the cleavage status of ZP2 and that binding at the surface of the zona is not sufficient to induce sperm acrosome exocytosis PMID: 20616279
    9. Results indicate that ZP2 and ZP3 traffic independently through the oocyte prior to assembly into the zona pellucida. PMID: 17047254
