Postmortem tissues are frequently used in forensic investigation, clinical studies, and biomedical research. It is well known that the shorter period from death to analyses provides the more accurate results. However, the longest postmortem interval that still provides the reliable data remains unclear. We performed serial analyses of postmortem changes in proteome profile, histology electrolyte contents, water composition, and enzyme activity in human vastus lateralis muscle from a male cadaver (died from a motorcycle accident). This uninjured muscle was sectioned into several 1-cm3cubes and stored in individual closed tubes at 4 or 25°C for 0, 2, 4, 6, 12, 24 or 48 h prior to proteomic, histological, chemical and biochemical analyses. At 4°C, the 2-DE proteome profile remained unchanged until 24 h, when some poorly focused protein spots and significant decrease in the total number of visualized spots were observed. These changes were detectable earlier (12 h) in the samples stored at 25°C. Profound vacuolization and autolysis started at 24 and 6 h for the samples stored at 4°C and 25°C, respectively.
