Serine Peptidase Inhibitor Kazal Type 1 (SPINT1), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as enzymatic analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.
  • Activity: Measured by its ability to inhibit trypsin cleavage of a fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2 (R&D Systems Cat. No. ES002); the IC50 value is <2nM
  • Formulation: Lyophilized in 140mM NaCl, 2.7mM KCl, 10mM Na2HPO4, 1.8mM KH2PO4, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween 80
  • Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2mg/mL or lower; aliquot and use as soon as possible
