COMPARATIVE STUDIES OF KERATIN COMPONENTS ON HAIRS OF ANIMALS AND HUMAN
动物的毛与人发角蛋白组分的比较研究

Hair keratins from a total of 50 individuals belonging to 10 families and 18 species have been analyzed by means of SDS-polyacrylamide gel electroph-oresis (SDS-PAGE). Animal hairs differ mainly from human hair in the range of low molecular weight components ( <18500 dalton). There are obviously differences among various animal species. Ailuropode melanoleuca hair is greatly different from Ailurus fulgens hair and Selenarctos thibetanus hair. Based on this observation, the paper describes a difference of keratin component from animal hairs, which provides useful information for hair comparision in animal taxonomy.
