Transforming Growth Factor beta 1, Human Recombinant, CHO

Transforming growth factor betas (TGFBetas) mediate many cell-cell interactions that occur during embryonic development. Three TGFBetas have been identified in mammals. TGFBeta1, TGFBeta2 and TGFBeta3 are each synthesized as precursor proteins that are very similar in that each is cleaved to yield a 112 amino acid polypeptide that remains associated with the latent portion of the molecule Store at -20℃ Source CHO Formulation Lyophilized from a sterile filtered solution containing 0.1 % trifluoroacetic acid (TFA) And trehalose (1:20 protein to Trehalose ratio). Purity Greater than 95.0% as determined by SDS-PAGE Biological Activity The ED50 as determined by the dose-dependent inhibition of IL-4-induced proliferation of HT-2 cells is 45.9pg/ml, corresponding to a specific activity of 2.2x107units/mg. Stability Lyophilized TGFB1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TGFB1 Human should be stored at 4°C betwe
