Half-life and degradation rate of hydrogen peroxide by catalase in the different experimental set-ups
| Experimental set-up | H2O2 half-life (t1/2)(minute) | H2O2 half-life (t1/2)(second) | First order rate constant (k) (10-3/s) |
|---|---|---|---|
| Cells without added catalase | 2.42 ± 0.18 | 145 ± 10.8 | 4.77 ± 0.06 |
| Cells with added catalase | 1.87 ± 0.28 | 112 ± 16.8 | 6.17 ± 0.11 |
| Catalase absorbed at walls of the cell culture plate | 6.50 ±0 .32 | 390 ± 19.5 | 1.78 ± 0.04 |
Data are expressed as the mean ± SD.
