The murine Ss protein has been isolated and purified. Using specific antisera, the radiolabeled protein has a mol wt of 120,000 in sodium dodecyl sulfate polyacrylamide gels. It is composed of two basic subunits of 23,000 and 14,000 daltons. The smaller molecular weight subunit contains a single disulfide bridge, is devoid of carbohydrate, and may represent the murine equivalent of beta2-microglobulin.
小鼠Ss蛋白已被分离和纯化。使用特异性抗血清,该放射性标记蛋白在十二烷基硫酸钠聚丙烯酰胺凝胶中的分子量为120,000。它由两个分子量分别为23,000和14,000道尔顿的碱性亚基组成。分子量较小的亚基含有一个二硫键,不含碳水化合物,可能相当于小鼠的β2-微球蛋白。
