Comparison of platelet-derived growth factor prepared from release products of fresh platelets and from outdated platelet concentrates.
Platelet-derived growth factor was isolated from the release products of washed, human platelets and from freeze-thawed outdated platelet concentrates. On the basis of sodium dodecyl sulphate polyacrylamide gel electrophoresis and amino acid sequence determination we conclude that platelet derived growth factor released from platelets by the agonist thrombin (EC 3.4.4.13) is structurally similar to that isolated from lysed platelets and from platelet concentrates stored for more than 72 hr at room temperature.
