Fig. 4. Effects of human RNA on biofilm formation.

Fig. 4

a A profile of human RNA isolated from total blood using ISOGEN-LS is shown. The purified RNA was treated with the indicated enzymes or left untreated (Control) and subsequently analyzed using agarose gel electrophoresis. b The effects of human RNA on biofilm formation by MR10 in RPMIG. Biofilm biomass is shown as mean and standard deviation (error bar) from three independent experiments. **P < 0.01. c, d Biofilm formation in polyurethane tubes was analyzed under continuous flow conditions. MR10 was grown in PNG supplemented with (c) or without human RNA (d). Representative images of three independent experiments are shown. The arrows indicate the directions of flow. Scales indicate 1 cm.
