Rat lenses stored for extended periods at -20°C showed degradation and eventual disappearance of vimentin. This may have been caused by the rupture of cells and/or organelles by growing ice crystals and the subsequent release and diffusion of proteases. Besides the disappearance of vimentin there was also a decrease in the intensity of the βB1 polypeptide after 3 months storage. The observations reported herein are generally qualitative in nature, but should serve to alert other investigators of a potential problem.
