Assay 1: Fully biologically active when compared to standard. The ED₅₀ as determined by the dose- dependent stimulation of the proliferation of murine NFS-60 cells is less than 5.0 ng/ml, corresponding to a specific activity of >2x10⁵ IU/mg.

Assay 2: The ED₅₀ as determined by a cell proliferation assay using human TF-1 cells is less than 0.05 ng/ml, corresponding to a specific activity of >2.0x10⁷ IU/mg.

This product is an active protein and may elicit a biological response in vivo, handle with caution.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at -20 °C. Further dilutions should be made in appropriate buffered solutions.
