Figure 2. Sodium dodecyl sulfate polyacrylamide gel electrophoresis of the lens water soluble protein fraction. An equal amount of protein (30 μg) was loaded on 12% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS–PAGE). The first right lane indicates the molecular weight marker; Group I lane represents the protein profile of the normal untreated lens; Group II, the selenite-treated group; Group III, the selenite+saffron-treated group. In the normal untreated lens water-soluble fraction (WSF), the prevalence of proteins with a molecular mass of 19–30 kDa (characteristic of crystallins) is shown. Selenite treatment led to a significant reduction (~35%) in these proteins, which was prevented by saffron coadministration.
