摘　　要：用改进的ＳＤＳ凝胶电泳法对实验室生产的水解丝蛋白产品的分子量进行了测定。测定表明该产品分子量分布在４３０００～２９００的范围，分子量在１００００以下的低分子蛋白成分含量高于５０％。The molocular weights of the silk's protein hydrolysate prepared in the laboratory were diterminated by SDS condensed gum electrophoresis.The experimental results show that molecular weights distribution of the samples is between 43000～2900 and the small molecular(below 10000 molecular weight) protein content of the samples is more than 50%.
