Platelet yield, recovery and platelet-rich plasma volume after the first blood centrifugation step. (A) Platelet yield, (B) recovery and (C) PRP1= platelet-rich plasma after the first blood centrifugation step. Values expressed as mean ± standard deviation. Different letters indicate statistically significant differences (analysis of variance followed by Tukey post-hoc test, n = 3, α = 0.05). Condition 1: 240 × g, 8 minutes, 16°C; condition 2: 360 × g, 16 minutes, 16°C; condition 3: 300 × g, 5 minutes, 12°C; condition 4: 300 × g, 12 minutes, 5°C; condition 5: 300 × g, 12 minutes, 12°C.
