Unformatted text preview: f. at high shear str ess, viscosity of cytoplasm is low and exhibits little resistance to bead movement Experiment al analy sis of diffusion barriers/ crowdedness of cy t oplasm: 1. Prepar e uniform-sized pr eparations of fluor escent dextran particles of different sizes from 5100nm in diameter. 2. Microinject into cultured cell. 3. Measure diffusion coefficient --> dextran par ticles with diameter <50nm exhibited fr ee diffusion --> >50nm exhibited significantly slower diffusion rates than in...
