  • 蛋白标签：
    C-terminal hFc-Myc-tagged
  • 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.
  • 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, pH 8.0.
  • 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°C/-80°C. 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：
    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：

    Human UL16-binding protein 1(ULBP1) amino acid Gly26-Gly216, with an N-terminal linker, an internal linker, and a C-terminal FC-Myc-tag, was expressed in mammalian cells. The product is the C-terminal FC-Myc-tagged recombinant human ULBP1 protein. It is an active protein with high purity (> 90%, SDS-PAGE) and low endotoxin (< 1.0 EU/ug protein, LAL method). In the functional ELISA, this ULBP1 protein can bind to the immobilized KLRK1 protein with an EC50 constant of 228.5-427.6 ng/ml. In the LSPR assay, this ULBP1 protein can bind to the human KLRK1 protein captured on the COOH chip with an affinity constant of 2.27 nM. And it is available now.

    ULBP1 is a ligand for the immune system-activating receptor NKG2D. ULBP1 binds to and activates the NKG2D receptor, mediating NK cell cytotoxicity.
