Figure 1. Two-dimensional electrophoresis maps of urea-soluble protein fractions from lenses of 3-, 12-, and 62-week-old Wistar and OXYS rats. Red circles mark cataract-specific spots of interest (SOI_cs; spot intensity in OXYS maps are more than 50% higher than in Wistar maps); yellow circles mark age-related spots of interest (SOI_ar; spot intensity in OXYS maps are more than 50% lower than in Wistar maps).
