Figure 6. Occurrence of β1-crystallin in lenticular urea-soluble protein fractions in different groups of Wistar rats. A typical western blot showing age-dependent relative concentrations of β1-crystallin in the urea-soluble protein fractions of Wistar rat lenses. A: An equal amount of protein was loaded in each lane and subjected to electrophoresis. Blots were incubated with β1-crystallin antibody. B: Bnd intensity of β1-crystallin levels relative to 10 day-old rat lenses. C: Linear regression analysis revealed a significant negative correlation between βB1-crystallin and the urea-soluble to soluble protein ratio. (▲) Values in 10 day-old rat lenses; (□) Values in 16 day-old rat lenses; (●) Values in 30 day-old rat lenses; (♦) Values in 90 day-old rat lenses; (×) Values in 180 day-old rat lenses; (■) Values in 365 day-old rat lenses; (○) Values in the lenses of 16 day-old rats that had been administered selenite on post-partum day 10.
