Lysosomes in Lymphoid Tissue
The density-distribution patterns of various enzymes and of labeled materials have been determined by isopycnic centrifugation in a sucrose-0.2 M KCl gradient on homogenates of lymphoid tissues from rats injected with Triton WR-1339, (14)C-labeled dextran, (51)Cr-labeled erythrocytes, and cortisol. The results confirm and extend the conclusion, derived from previous investigations on normal ani...
متن کاملLYSOSOMES IN LYMPHOID TISSUE I. The Measurement of Hydrolytic Activities in Whole Homogenates
Methods have been developed for the quantitative assay of cytochrome oxidase, esterase, and 11 acid hydrolases in rat-spleen homogenates. These methods seem to be applicable also to other lymphoid tissues. Preliminary studies, extended to nine of the acid hydrolases, indicate that these enzymes occur in partly latent and sedimentable form and that they can be unmasked and rendered soluble by so...

متن کاملLysosomes in Skeletal Muscle Tissue
Postnuclear supernates from homogenates of skeletal muscle from rats subjected to starvation, injections of Triton WR-1339, dextran-500, and dextran + corticosterone were fractionated by means of rate and isopycnic zonal centrifugation in sucrose-0.02 M KCl gradients. Zonal fractions were analyzed for protein, RNA, cytochrome oxidase, and up to six acid hydrolases. The results indicate the pres...
متن کاملLymphoid Tissue in the Lizard
The present paper reports a study of lymphoid tissue in lizards and describes some of the characteristics of their lymphoid tissue. Lymphoid tissue in other reptiles was studied in turtles by K o n d o (1937) and M or i (1941) and in snakes by Mori (1941), T a k a wa (1943) and K o t an i (1959). Recently, K i h a r a (1954) subdivided the lymphoid tissue, in general, into two : the subepitheli...
