Kinase experiment: |
Enzyme activity is determined photometrically using a temperature controlled multi-mode plate reader or alternatively in a UV/Vis spectrophotometer. Reactions are initiated by addition of the enzyme. Enzyme activity is measured over a period of 10 min at 25°C at the appropriate wavelength for the substrate. One unit (1 U) is defined as the amount of enzyme that converts 1 µmol substrate per minute. Various H2O2 concentrations (0-1250 µM, enzyme concentrations (0.27-54 nM) and substrate concentrations are used to determine the enzyme activity. The activity of rPsaDyP vs ABTS is determined in 100 mM sodium acetate buffer at pH 3.8 and a final H2O2 concentration of 125 µM. Production of the ABTS cation radical is studied at 420 nm (ε420 36,000 L mol-1 cm-1)[2]. |

ABTS is a radical cation and a substrate of peroxidases, including horseradish peroxidase (HRP).1 It has commonly been used to assess antioxidant capacity in the Trolox equivalent antioxidant capacity (TEAC) assay.2,3 It has a blue color in the presence of sodium persulfate or metmyoglobin but decolorizes upon incubation with antioxidants, and the antioxidant capacity can be determined spectrophotometrically. ABTS has also been used as an enzyme substrate in ELISAs.4,5 Upon incubation with a peroxidase, it produces a soluble green product that can be quantified by colorimetric detection at 405 nm.1
