  • Activity: Measured by its binding ability in a functional ELISA: 1. Immobilized human IGF2 at 10μg/mL (100μL/well) can biotinylated human IGFBP3-His, the ED50 of can biotinylated human IGFBP3-His is 18ng/mL; 2. Immobilized human IGF1 at 10μg/mL (100μL/well) can biotinylated human IGFBP3-His, the ED50 of can biotinylated human IGFBP3-His is 24ng/mL
  • Formulation: Lyophilized in PBS, pH 7.4, 5% Mannitol, 5% Trehalose, and 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
