Figure 2From: A novel highly thermostable xylanase stimulated by Ca2+ from Thermotoga thermarum: cloning, expression and characterizationEffects of cations and reagents on the activity of purified Xyn10A. The final concentration of cations was 1 mM. The final concentration of reagents detailed as below, 0.05% Tween 60 and Tris, 0.1% SDS. The activity of the experiment without cation or reagent was defined as 100%. Values shown were the mean of duplicate experiments, and the variation about the mean was below 5%.Back to article page
