Apparent heterogeneity of hepatic lysosomes due to membrane-bound acid phosphatase.
Hepatic lysosomes have been fractionated by rate sedimentation and by isopycnic banding. In all experiments, the distribution of acid phosphatase differed from that of the other lysosomal enzymes. Evidence is presented that this difference is due not to the separation of lysosomes from different cell types, but simply reflects the membrane location of a part of the acid phosphatase.
