Aqueous environments in living cells are crowded, with up to >50 wt% small and macromolecule-size solutes. We investigated quantitatively one important consequence of molecular crowding--reduced diffusion of biologically important solutes. Fluorescence correlation spectroscopy (FCS) was used to measure the diffusion...

Unfolded states of ribonuclease A were used to investigate the effects of macromolecular crowding on macromolecular compactness and protein folding. The extent of protein folding and compactness were measured by circular dichroism spectroscopy, fluorescence correlation spectroscopy, and NMR spectroscopy in...

The non-ideal properties of solutions containing high concentrations of macromolecules can result in enormous increases in the activity of the individual macromolecules. There is considerable evidence that macromolecular crowding and confinement not only occur in cells, but that these are...

Ficoll PM70 is an important branched polysaccharide polymer with a variety of applications in biology and biophysics. The accepted picture for the aqueous solutions of this polymer is that of a polydisperse nearly spherical suspension with a molecular weight of...

Macromolecular crowding has been proposed as a mechanism by means of which a cell can sense relatively small changes in volume or, more accurately, the concentration of intracellular solutes. According to the macromolecular theory, the kinetics and equilibria of enzymes...
