<p>A polypeptide transforming growth factor found in porcine platelets, having activity in the TGF-β assay and a molecular weight of about 25 kDa. The factor is a heterodimer, one chain of which has an N-terminal sequence very different from human platelet TGF-β, and the other chain of which has an N-terminal sequence identical to that of human platelet TGF-β. The factor is purified using gel filtration and reverse phase HPLC.</p> |
