High-activity: The ED₅₀ as determined by a cell proliferation assay using murine balb/c 3T3 cells is less than 1 ng/mL, corresponding to a specific activity of > 5.0 × 10⁶ IU/mg.

High-activity: Immobilized Human BDNF, No Tag at 1 μg/ml (100 μl/well) on the plate. Dose response curve for Human TrkB, His Tag with the EC₅₀ of 0.39 μg/ml determined by ELISA.

High-activity: The ED₅₀ as determined by a cell proliferation assay using human TF-1 cells is less than 150 ng/mL, corresponding to a specific activity of > 6.6 × 10³ IU/mg.
