Abstract
A polypeptide transforming growth factor found in porcine platelets, having activity in the TGF-.beta. 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-.beta., and the other chain of which has an N-terminal sequence identical to that of human platelet TGF-.beta.. The factor is purified using gel filtration and reverse phase HPLC.
