Figure 4. Increasing platelet concentration causes the integration of two peaks into one.

A: Curves of thrombin generation obtained in a typical experiment with the plasma of a healthy donor containing 1.6% of DMSO and different concentrations of platelets. Coagulation was triggered with 2 pM of TF. B: The dependence of the mean ETP values and SD on platelet concentration for healthy donors (n – number of donors; * - difference between PRP and PPP is significant (Student's t-test, P<0.01)).
