From: In vitro evaluation of novel antimicrobial coatings for surgical sutures using octenidine
Metabolic cell activity of fibroblasts in the presence of eluates from octenidine coated sutures via WST-1 proliferation assay. L-929 mouse fibroblasts were incubated with suture eluates and used references: lauric acid (LA), palmitic acid (PA), uncoated sutures (Gunze), and Vicryl® Plus. All values were referred to cellular growth control, pure L-929 cells with culture media. Dashed line at 70 % pictures the level for acceptable lowering of metabolic activity according to ISO 10993–5:2009 in order to declare biocompatibility of medical devices
