Plasma samples of 270 foxes from 45 complete families (14 of arctic foxes, 28 of silver foxes and 3 with arctic x silver fox hybrid offspring) were analysed by a method of two-dimensional agarose gel (pH 5.4)-horizontal polyacrylamide gel (pH 9.0) electrophoresis followed by general-protein staining of gels. Genetic polymorphism of three plasma proteins, tentatively designated prealbumin (Pr), postalbumin 1 (Pa1), and pretransferin 1 (Prt1), was observed. In silver foxes, Pa1 and Prt1 showed a high degree of polymorphism, each with 3 common alleles, while Pr showed a scarce polymorphism. The arctic foxes were monomorphic for Pr and Prt1 and showed a scarce Pa1 polymorphism. The Prt1 phenotype of arctic foxes showed identical mobility with one of the Prt1 variants of silver foxes.
采用二维琼脂糖凝胶(pH 5.4)-水平聚丙烯酰胺凝胶(pH 9.0)电泳法,随后对凝胶进行总蛋白染色,分析了来自45个完整家庭的270只狐狸的血浆样本(14只北极狐、28只银狐和3只北极狐与银狐杂交后代)。观察到三种血浆蛋白的遗传多态性,暂定为前白蛋白(Pr)、后白蛋白1(Pa1)和前转铁蛋白1(Prt1)。在银狐中,Pa1和Prt1表现出高度多态性,各有3个常见等位基因,而Pr表现出罕见的多态性。北极狐的Pr和Prt1是单态的,Pa1多态性较少。北极狐的Prt1表型与银狐的一种Prt1变体具有相同的迁移率。
