Dose-dependent increase in DCFH oxidation rate (as measured by changes in fluorescence per minute) after incubation of specific amount (2.5 ug) of HDL (light gray columns), or LDL (solid black columns) that were isolated by ultracentrifugation from a healthy donor with increasing concentration of DHR (1, 10, 20, 30, 40, 50 uM). Fluorescence intensity was determined after 1 h of incubation at 37° C. The values represent means ± SD of quadruplicate samples.
