Samples of white muscle and liver tissue from walleyes Stizostedion vitreum were Subjected to various storage regimes to determine the effect of Storage temperature on the biochemical integrity of three proteins commonly assayed in electrophoretic analyses (white muscle malate dehydrogenase, white muscle myogen, and liver isocitrate dehydrogenase). Samples stored on wet ice (0°C) for 24 h, followed by Storage for up to 306 d in a Standard freezer (–15°C), provided electrophoretic results similar to those for samples that were stored in liquid nitrogen (–195°C) immediately after death of the Subject fish. Tissue samples Stored in an ultracold freezer (–70°C) for longer than 3 years Showed no protein degradation.
