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
