Cytoplasm viscosity
WebThe shear-thinning liquid drop model assumes that the cytoplasm of a cell acts as non-Newtonian fluid. This model accounts for changes in cytoplasmic viscosity with applied shear rates. Specifically, there is a decrease in cytoplasm viscosity with increasing aspiration pressure, that is, shear rate (Needham and Hochmuth, 1990; Tsai et al., 1993 ... WebDec 17, 2013 · Abstract.

While the cytoplasm of cells is a complex uid comprised of proteins, cytoskeletal laments, membranes, and other macromolecules, the cytoplasmic viscosity is typically de ned as the viscosity experienced by small tracer particles such as GFP or uorescent quantum dots introduced into cells [13, 14]. WebJan 9, 2024 · The phosphorescence lifetime of Pt[L]Cl in the cytoplasm increased from 3.5–5 to 4–6 µs, again indicating an effect of ionizing radiation on the viscosity of cells.
WebMay 11, 2011 · Small protein molecules almost do not experience the cytoplasm viscosity while moving within the cell. Scientists have now shown that the effect can be described … WebDec 2, 2014 · We demonstrate that the size dependence of diffusion coefficients, anomalous exponents, and the effective viscosity experienced by biomolecules in the cytoplasm is fine-tuned by the intermolecular interactions. Accounting only for excluded volume in these potentials gives a weaker size-dependence than that expected from experimental data.
WebFeb 3, 2024 · Overall, our data were more consistent with heterogeneity in cytoplasm viscosity (Fig. 4) than a two-state system of mobile and immobile particles. In the Doppelgänger simulations with heterogeneous viscosity, nonergodicity arises from the fact that particles within distinct spatial domains exhibit different diffusion rates.
