UL16-binding protein 1 (ULBP1) (Active), human, recombinant

Organism: Homo sapiens (Human). Source: Mammalian cell. Expression Region: 26-216aa. Protein Length: Full Length of Mature Protein. Tag Info: C-terminal hFc-Myc-tagged. Target Protein Sequence: GWVDTHCLCY DFIITPKSRP EPQWCEVQGL VDERPFLHYD CVNHKAKAFA SLGKKVNVTK TWEEQTETLR DVVDFLKGQL LDIQVENLIP IEPLTLQARM SCEHEAHGHG RGSWQFLFNG QKFLLFDSNN RKWTALHPGA KKMTEKWEKN RDVTMFFQKI SLGDCKMWLE EFLMYWEQML DPTKPPSLAP G. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Less than 1.0 EU/ug as determined by LAL method. Biological Activity: ?Measured by its binding ability in a functional ELISA. Immobilized KLRK1 (CSB-MP012474HU1) at 10 µg/ml can bind human ULBP1, the EC50 of human ULBP1 protein is 228.5-427.6 ng/ml. ?Human KLRK1 protein Fc tag (CSB-MP012474HU1) captured on COOH chip can bind Human ULBP1 protein Fc/myc tag (CSB-MP887177HU) with an affinity constant of 2.27 nM as detected by LSPR Assay. Form: Lyophilized powder. Buffer: Lyophilized from a 0.2 µm filtered PBS, 6% Trehalose, pH 7.4. Reconstitution: 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. Storage: 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. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Binds and activates the KLRK1/NKG2D receptor, mediating natural killer cell cytotoxicity. Reference: n/a. Function: nan
