Platelet derived growth factor (PDGF) has been partially purified from porcine platelets. Purification steps included heparin-agarose chromatography of the material released by thrombin-stimulated washed porcine platelets and Blue-Sepharose chromatography. Preparative isoelectric focusing showed that isoelectric point of porcine PDGF is at pH 10.0–11.0 and elution experiments from sodium dodecyl sulfate (SDS) polyacrymlam de gels indicated that its molecular weight is close to 30 kD. The immunoglobulin fraction prepared from anti-human PDGF serum inhibited the mitogenic activity of porcine PDGF. These experiments suggest a homology of porcine and human PDGF. Porcine platelet factor 4 and porcine platelet basic protein were devoid of significant mitogenic activity.
