Plasma treatment of rAaeUPO was performed either without
or in the presence of 1 mg ml-1 SodA for 5 min using 100 μl. Subsequently, samples were
diluted 1:10 in sodium acetate buffer (pH 5.5) containing 2.5 mM ABTS. After addition of H2O2
at a final concentration of 1 mM, A405 was followed for 5 min. Activities were calculated from
the initial slope. The residual activity was defined as the activity of the treated samples divided
by the activity of the respective untreated samples. n=2.
