Figure 2. Lens enzymes distribution. Bovine lenses were dissected and different enzyme activities were assayed in each section as described in Methods. Slices “a” and “f” refer to the anterior and posterior sides, respectively. GSHS: glutathione synthetase; γ-GCS: γ-glutamyl cysteine synthetase; γGT: γ-glutamyl transferase; LAP: leucine amino peptidase. Values reported are the mean of three different experiments; the error bars represent the standard error of the mean. Significance was evaluated with respect to the slice displaying the lowest activity. (*): p<0.05; (**): p<0.01; (***): p<0.001.
