Fresh porcine blood platelets, subjected to ethanol acid extraction and purification on DEAE-Sephadex A-50 and CM-Sephadex C-50, were used to obtain partially purified, cationic PDGF (pI 8.5-10) of Mr 38,000 and biological activity 10(4) U/ml. Reduction of porcine PDGF with 2-mercaptoethanol revealed the presence of two polypeptides with Mr 18,000-22,000.
