TGF b 1 Human Recombinant

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.

TGFB1 Human Recombinant produced in CHO cells is a glycosylated homodimeric polypeptide chain containing 2 x 112 amino acids and having a total molecular mass of 25.6kDa. The TGFB1 is purified by proprietary chromatographic techniques.

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.
