Buoyant density constancy of Schizosaccharomyces pombe cells.
Buoyant densities of cells from exponentially growing cultures of the fission yeast Schizosaccharomyces pombe 972h- with division rates from 0.14 to 0.5 per h were determined by equilibrium centrifugation in Percoll gradients. Buoyant densities were independent of growth rate, with an average value (+/- standard error) of 1.0945 (+/- 0.00037) g/ml. When cells from these cultures were separated ...
متن کاملCharacterization of hog cholera virus. I. Determination of buoyant density.
Horzinek, Marian (Tierärztliche Hochschule, Hannover, West Germany). Characterization of hog cholera virus. I. Determination of buoyant density. J. Bacteriol. 92:1723-1726. 1966.-Hog cholera virus was subjected to cesium chloride density gradient centrifugation. Most of the infectious activity was detected in fractions with densities between 1.15 and 1.20 g/ml, with a peak at 1.16 g/ml. Infecti...
متن کاملHarvesting of bone marrow mesenchymal stem cells from live rats and the in vitro differentiation of bone marrow mesenchymal stem cells into neuron-like cells
In the bone marrow, there are certain populations of stem cell sources with the capacity to differentiate into several different types of cells. Ideally, cell transplants would be readily obtainable, easy to expand and bank, and capable of surviving for sufficient periods of time. Bone marrow mesenchymal stem cells (BM-MSCs) possess all of these characteristics. One of the most important benefi...
متن کاملBuoyant density and morphology of rubella hemagglutinin.
Rubella virions demonstrated by negative-contrast electron microscopy have recently been reported to range from 500 to 750 A in diameter and to have amorphous pleomorphic envelopes (J. M. Best et al., Lancet 2:237, 1967). Consonant with these observations, sedimentation studies have indicated a diameter of 850 A and ultrafiltration experiments, 900 A (B. Russell et al., J. Gen. Virol. 1:305, 19...
متن کاملFicoll-Hypaque separation of bone marrow cells.
Levitt et aP and Greenberg et al’ have recently described elegant immunologic methodologies for selectively isolating T lymphocytes’ or hematopoietic progenitor cells2 from small aliquots of human marrow. In both cases the initial marrow manipulation, following aspiration, involved selective isolation of light-density mononuclear cells using Ficoll-Hypaque (I .077 ± 0.003 g/dL) gradients. Poten...
