摘要

1. 唾液酸酶消化导致猪转铁蛋白的电泳迁移率降低,但不破坏其结合铁的能力。电泳迁移率的降低分两个不同的步骤发生。TfA和TfB的最终唾液酸酶消化产物的迁移率表明,TfA和TfB的迁移率的差异不是由于它们各自含有的唾液酸的量的差异。在高压三柠檬酸凝胶分析下,观察到TfA和TfB的三个区域之间的迁移率差异似乎不是由于每个区域所拥有的唾液酸的量。

THE EFFECT OF SIALIDASE ON PIG TRANSFERRINS.
1. Sialidase digestion resulted in a decreased electrophoretic mobility of pig transferrins without destroying their ability to bind iron.2. The decrease in electrophoretic mobility occurred in two distinct steps.3. The migration rates of the final sialidase digestion products of TfA and TfB suggest that the difference in mobilities of TfA and TfB is not due to a difference in the amount of sialic acid which each contains.4. The mobility differences between the three zones observed for both TfA and TfB under high voltage Tris–citrate gel analyses do not appear to be due to the amount of sialic acid possessed by each.
