Genotype | CuZn-SOD Activity (%) | |
---|---|---|
Blood (n = 9) | Brain (n = 3) | |
Wt | 100 | 100 |
Sod1+/−uc | 53.1 ± 1.1 | 52.2 ± 2.3 |
Sod1+/−cep | 61.6 ± 5.8 | 47.7 ± 4.6 |
Sod1−/−cep | 5.4 ± 7.5 | 6.6 ± 7.6 |
CuZn-SOD activity was measured by a method based on cytochrome C reduction (McCord and Fridovich, 1969). Each value represents mean ± SEM of the percentages of CuZn-SOD activity, compared with Wt.
