Figure 4. Concentration and content of ubiquinones in rat lens regions
Four separate pools of capsules (epithelium), cortex, and nucleus, each from 8-10 lenses of 50 day old Sprague-Dawley rats, were weighed and homogenized. The ubiquinones were then extracted and quantitated by HPLC. A: Concentration (μg/g lens region) of total ubiquinones (Ub-9 plus Ub-10). B: Content (ng/lens) of total ubiquinones (Ub-9 plus Ub-10). Numbers in parentheses are the percentage of Ub-10 of the total ubiquinone; the remainder was Ub-9. Error bars represent the standard error of the mean.
