Supplementary Figure 6: Dependence of the FRET ratio on the hydrodynamic radius of PEG.
From: A sensor for quantification of macromolecular crowding in living cells
Conditions: 10 mM NaPi, pH 7.4. NaCl was omitted to prevent coacervate formation. The hydrodynamic radii1,2 were used to calculate the total PEG volume for 0.1 g PEG (Fig. 1d). The error bars are standard deviations from three independent experiments.
