Abstract

Lysosome-rich fractions were isolated from rat liver homogenates. In some fractions the lysosomes were separated from the contaminating mitchondria by the use of discontinuous Ficoll/sucrose gradients. Some glycogen was associated with lysosome fractions. This glycogen was of very large molecular size and of a quite different molecular-weight distribution from that isolated from the cytosol. It is suggested that appreciably more than 10% of cellular glycogen is located within the lysosome.

摘要

从大鼠肝脏匀浆中分离出富含溶酶体的组分。在一些组分中,通过使用不连续的菲可/蔗糖梯度将溶酶体与污染的线粒体分离。一些糖原与溶酶体组分相关联。这种糖原分子尺寸非常大,其分子量分布与从细胞质溶胶中分离出的糖原截然不同。据推测,细胞内超过10%的糖原位于溶酶体内。
