Figure 8. Protein carbonyl content in soluble protein fraction of lens. Protein carbonyl groups of soluble protein fraction of different groups were assayed by reactivity to 2,4-DNPH as described in the Methods section. Data are mean±SD (n=4). Different superscripts above the bars denote that data are significantly different among the groups.
