0.6 IU/μl. Unit Definition: One unit is defined as the amount of enzyme needed to cleave 100 μg of fusion protein in 16 hours to 90% completion at 4°C in a buffer containing 50 mM Tris-HCl, pH 7.0, 150 mM NaCl, 1 mM EDTA, and 1 mM DTT.
The ED50 was determined by the dose-dependent stimulation of the proliferation of murine Balb/3T3 cells is < 0.01 ng/ml, corresponding to a specific activity of >1 x 10ˆ8 units/mg.
Assay #1: Measured by its ability to induce alkaline phosphatase production by ATDC-5 Cells, The ED50 for this effect is typically 0.07-0.2 µg/mL. <br/>Assay #2: Measured by its ability to induce alkaline phosphatase production by C2C12 cells, The ED50 for this effect is typically 0.2-1 µg/mL.
ED50 < 10μg/, measured by its ability to induce alkaline phosphatase production by CCL-226 cells, corresponding to a specific activity of > 100 units/mg.
ED50 < 6 µg/ml, measured in stimulation of alkaline phosphatase activity using CCl-226 cells. Up to 180% stimulation of alkaline phosphatase activity was observed at 10.0 ug/ml.
The ED50, calculated by the dose-dependant proliferation of murine BALB/c 3T3 cells is less then 2 ng/ml, corresponding to a specific activity of 5.0×10ˆ5 IU/ mg.
ED50 <0.6ng/ml, measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblasts in serum-free medium and CellTiter-Glo cell viability assay, corresponding to a specific activity of >1.7 x 10ˆ6 units/mg.
