Fig. 6. Longevity of AmSOD1 activity. Purified His-AmSOD1 was tested for its longevity both at room temperature and 4 ◦ C for different time period (20, 40, 60, 80, 100, 120 1st 140 days). The ratio enzyme activity was determined based on the activity of enzyme before incubation. Each data point represents the mean ± SD obtained from three independent reactions.
