Effects of various detergents on the activity of AMZ-tk.

Detergents	Concentration	Relative activity (%)
SDS	2%	56.1 ± 0.56
Triton	2%	52.7 ± 0.78
Tween	2%	60.7 ± 6.58
Ariel	2%	88.3 ± 5.68
Wheel	2%	79.5 ± 5.52
Surf excel	2%	72.0 ± 6.48
OMO	2%	75.6 ± 5.24
Liby	2%	73.5 ± 8.61
Tide	2%	65.9 ± 6.15

The enzymes were pre-incubated with detergents for 60 min at 37°C and the remaining protease activities were measured under standard conditions. The activity is expressed as a percentage of the activity level in the absence of additives. Data were statically analyzed by one-way ANOVA (p < 0.05).
