Figure 2. Two-dimensional gel electrophoretic separation of individual protein spots present in WI-UI protein fractions of a normal lens and a cataractous lens

Two-dimensional gel electrophoretic profiles of water insoluble-urea insoluble-protein fractions from (A) normal lens from a 68-year-old donor, and (B) cataractous lens with nuclear opacity from a 61-year-old donor. The numbers with arrows point to individual protein spots (starting from the lowest to the highest molecular weights) of a normal lens and a cataractous lens.
