The size and shape of the recombinant murine small heat shock protein, hsp25, have been analyzed by hydrodynamic and electron microscopic methods. According to these studies recombinant hsp25 exists in large complexes with a sphere-like shape and diameters of 15-18 nm. The molecular mass of these complexes amounts to about 730 kDa indicating that they are composed of about 32 monomers.
