Storage and Stability
Human M-CSF is fully biologically active when compared to standards. The ED50 as determined by the dose-dependent stimulation of the proliferation of murine M-NFS-60 cells is ≤1ng/ml, corresponding to a specific activity of ≥1x10e6 units/mg. . Lyophilized and reconstituted products are stable for 6 months after receipt at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
