EV-associated PPL activity measured by PPL activity assay. (A) EVs reduce the PPL clotting time of SPP, mainly those in 20K pellets, thus increasing the PPL activity. The blue and dotted lines represents the reference PPL clotting time (mean ± SD, n = 12) of SPP without addition of EVs. (B) The 20K pellets showed tendency towards larger particles correlating with increased PPL activity, although this was not significant. (C) A significant correlation between PPL clotting time and thrombin generation using PRP reagent (containing no PL) was observed, but this disappeared when using PPPlow reagent (containing PL). *P < 0.001.
