Figure 2 In vitro incubation of autologous platelet clots. After 60 minutes of incubation at 37°C, the PRF clot remained solid while either APG clot formula liquefied almost completely. APG, Autologous platelet gel; APG-TXA, APG plus tranexamic acid; APG-AP, APG plus aprotinin; PRF, platelet-rich fibrin.
