Abstract: | Synopsis Purified preparations of epithelial cells have been made from the guinea-pig small intestine. Homogenates of these preparations have been analysed by centrifugation in a zonal rotor. The results confirm the presence of lysosomes in these cells and indicate the existence of catalase particles which equilibrate in a sucrose gradient at a density of between 1.21 and 1.23 and which have a different distribution from other subcellular particles except lysosomes. Injection of Triton WR-1339 into fasting animals enables the separation of lysosomes and catalase particles. |
