TGF beta 3 Recombinant Protein

The ED50 was determined by TGF - B3’s ability to inhibit the mouse IL - 4 - dependent proliferation of mouse HT - 2 cells is ≤ 0.05 ng/mL, corresponding to a specific activity of ≥2 x 107 units/mg.

The lyophilized TGF beta 3 recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted TGF beta 3 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing TGF beta 3 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.
