Proteins from an adult DKO lenses were largely water-insoluble. Due to insufficient soluble protein, the Rh values from viscosity measurements for the DKO lenses were used. The DKO lens proteins exhibited a shoulder before the main β-crystallin peak (Figure 4C and D). An additional peak with an estimated molecular weight of > 10×106 was observed in 9-day-old DKO lenses (Figure 4B).
