  • 蛋白标签：
    N-terminal 6xHis-SUMO-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：
    If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
    Note: If you have any special requirement for the glycerol content, please remark when you place the order.
    If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
  • 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：
    3-7 business days
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • 产品描述：
    Recombinant Human Hyaluronidase PH-20(SPAM1) is a partial length protein expressed with N-terminal 6xHis-SUMO-tagged in the E.coli. Its expression region corresponds to 36-490aa of human SPAM1 protein. Its purity was determined by SDS-PAGE and reached up to 90% and presented a molecular mass band of 67.9 kDa on the gel. This recombinant SPAM1 protein may be used to synthesize antibodies against SPAM1. SPAM1 is involved in sperm-egg adhesion. Upon fertilization, sperm must first penetrate a layer of cumulus cells that surrounds the egg before reaching the zona pellucida. The cumulus cells are ...显示更多

  • 功能：
    Involved in sperm-egg adhesion. Upon fertilization sperm must first penetrate a layer of cumulus cells that surrounds the egg before reaching the zona pellucida. The cumulus cells are embedded in a matrix containing hyaluronic acid which is formed prior to ovulation. This protein aids in penetrating the layer of cumulus cells by digesting hyaluronic acid.
