FIG. 2.
Catalase enzyme activity assay. Catalase enzyme activity was quantitated in extracts of whole flies of the indicated genotypes. (A) Control lines. (B) Lines transgenic for FLP1 and the indicated catalase overexpression construct insertions. (C) Repeat of experiment in panel B. (D) Lines transgenic for FLP1 plus the indicated catalase insertion plus the indicated SOD insertion. (E) Repeat of experiment in panel D. The data are the mean and standard deviation of triplicate assays. Statistically significant differences (P < 0.05) between HP and Co were determined with two-sided t tests and are indicated by an asterisk.
