The depletion attraction: an underappreciated force driving cellular organization.

Davide Marenduzzo1, Kieran Finan, Peter R Cook.   

Abstract

Cellular structures are shaped by hydrogen and ionic bonds, plus van der Waals and hydrophobic forces. In cells crowded with macromolecules, a little-known and distinct force-the "depletion attraction"-also acts. We review evidence that this force assists in the assembly of a wide range of cellular structures, ranging from the cytoskeleton to chromatin loops and whole chromosomes.
