Water soluble extracts from cataractous and normal salmonid lenses were subjected to thin-layer isoelectric focusing. The cataracts resulted from deficiencies of specific nutrients in diets fed to three species of salmonids as follows: (1) rainbow trout (Salmo gairdneri) fed a diet deficient in riboflavin; (2) Atlantic salmon (Salmo salar) fed a diet deficient in methionine; and (3) rainbow trout and lake trout (Salvelinus namaycush) fed a diet deficient in zinc. In all tests, the protein pattern of cataractous lenses differed from that of normal lenses. Each cataract caused by the different dietary deficiencies had a specific pattern of soluble lens proteins. Even though the general patterns of the soluble lens proteins for all three salmonids though the general patterns of the soluble lens proteins for all three salmonids studied were similar, a specific pattern was unique for each of the species.
对白内障鲑鱼和正常鲑鱼晶状体的水溶性提取物进行薄层层析等电聚焦分析。这些白内障是由于投喂给三种鲑鱼的饲料中特定营养素缺乏所致，具体如下：（1）虹鳟（Salmo gairdneri）投喂缺乏核黄素的饲料；（2）大西洋鲑（Salmo salar）投喂缺乏蛋氨酸的饲料；（3）虹鳟和湖鳟（Salvelinus namaycush）投喂缺乏锌的饲料。在所有测试中，白内障晶状体的蛋白质图谱与正常晶状体不同。由不同饮食缺乏引起的每种白内障都有特定的可溶性晶状体蛋白图谱。尽管所研究的所有三种鲑鱼的可溶性晶状体蛋白的总体图谱相似，但每种物种都有独特的特定图谱。
