Abstract
Starch gel electrophoresis of human transferrin treated with neuraminidase revealed a pattern of five bands whose intensities varied with neuraminidase concentration. Sialic acid analysis after starch block electrophoresis suggested that the bands represented the stepwise removal of sialic acid from the transferrin molecule. Evidence was also obtained for the purification of a particular genetic transferrin variant
摘要
用神经氨酸酶处理人转铁蛋白后的淀粉凝胶电泳显示出五条带的图谱，其强度随神经氨酸酶浓度而变化。淀粉块电泳后的唾液酸分析表明，这些条带代表了从转铁蛋白分子上逐步去除唾液酸的过程。还获得了纯化一种特定遗传转铁蛋白变体的证据。
