Activin A Recombinant Protein

The ED50 was determined by its ability to inhibit the proliferation of murine MPC - 11 cells is ≤ 2.0 ng/mL, corresponding to a specific activity of ≥ 5 x 105 units/mg.

The lyophilized Activin A recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted Activin A is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing Activin A recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
