The effect of platelet free plasma (PFP) preparation on clotting time. PFP from 10 volunteers were prepared using two different centrifugation protocols, (A) 2500×g for 15 min twice or (B) 3000×g for 10 min followed by 13,500×g. Clotting times were measured using the modified PPL assay. Panel (A) is a box plot of all ten volunteers combined for the two protocols, while panel (B) displays the individual values as mean of duplicate measures ± 1 SD.
