From: Antibacterial effects of platelet-rich fibrin produced by horizontal centrifugation
The antibacterial properties of solid and liquid layers obtained via leukocyte- and platelet-rich fibrin (L-PRF) and H-PRF protocols. a Illustration of the stratified sampling and incubation procedure. The total platelet-rich fibrin (PRF) clot was divided into five equal portions and then separated into solid and exudate components. b–d Photos and quantitative analysis of the inhibition zones of each L-PRF and H-PRF layer against S. aureus and E. coli after incubation for 24 h. *P < 0.05, **P < 0.01, and ***P < 0.001
