Lipid peroxidation in QD-treated cells. LLC-PK1 cells were treated for 3, 6, or 24 h with 10nM CdSe QD (A), 100nM InGaP QD (B), 5mM DEM positive control, or media negative control. Lipid peroxides in media were determined by TBARS assay and are expressed in MDA equivalents normalized to total protein. Data represent the mean ± SD, N = 3. * p ≤ 0.05, significantly different than media control by Student's t-test. The 5mM DEM positive control value was 8.13 ± 2.32 nmoles MDA equivalent/μg protein (mean ± SD) and was significantly different than media control, p ≤ 0.05, by ANOVA, and Dunnett's post hoc test.
