[Changes in human skeletal muscle proteins during autolysis studied by two-dimensional electrophoresis]

More than 100 various fractions were detected in human skeletal muscle proteins analyzed by O'Farrell two-dimensional electrophoresis. Main proteins were maintained well in individual preparations of muscle tissue after their storage within 4 days at 20 degrees. The protein fractions with molecular mass of 140-150 kD as well as alteration of other muscle proteins were found on electrophoregramms within 6 days of storage.
