Macrophage Plasma Membranes
Plasma membranes have been isolated from pure populations of rabbit alveolar macrophages which were swollen in water, fixed briefly with glutaraldehyde, disrupted by Dounce homogenization, and separated by sucrose gradient centrifugation. The recovered membranes exhibited good structural preservation and enzymatic activity; both morphologic and biochemical evidence indicated a high degree of pu...
متن کاملMacrophage Plasma Membrane
Rabbit alveolar macrophages were incubated in vitro with radioactive protein precursors. Plasma membranes were isolated from these cells, dissolved in phenol-urea-acetic acid, and separated by acrylamide gel electrophoresis. (3)H-leucine was rapidly incorporated into membrane protein. The rate of labeling with (3)H-leucine was markedly different from one protein band to another, indicating hete...
متن کاملHela Cell Plasma Membranes
A method for the preparation of HeLa cell plasma membrane ghosts is described. The purity of the plasma membrane fraction was examined by phase contrast and electron microscopy, by chemical analysis, and by assay of marker enzymes. Data on the composition of the plasma membrane fraction are given. It was observed that the distribution pattern of 5'-nucleotidase activity among the subcellular fr...
متن کاملPlasma Membranes of Mammalian Cells
The plasma membrane surrounding living cells "plays a role in intracellular metabolism, but what distinguishes this structure from other organelles is that the plasma membrane also mediaces interactions between the cell and its external environment. The simplest of these interactions maintain a desirable intracellular milieu by bringing in needed substances and getting rid of waste products. Th...
متن کاملPlasma Proteins in Hyaline Membranes
Hyaline membrane disease of the newborn has been a subject of ever-growing interest to paediatricians and pathologists as it is the major cause of death in newborn babies, particularly premature ones. Much more is known of the clinical picture and physiological changes in hyaline membrane disease, or respiratory distress syndrome of the newborn (Avery, 1962; Curtis, 1957; James, 1959; Miller, 1...
