In vitro free radical scavenging experiment
1. Dissolve ABTS in ultrapure water (7.4 mM, 0.4 mL);
2. K2S2O8 stock solution (2.6 mM, 1.43 mL);
3. Mix the two solutions and let stand at room temperature in the dark for 12 hours;
4. Dilute 50 times with anhydrous ethanol;
5. Detect the absorbance at 734 nm.
A micro-technique of enzyme-linked immunosorbent assay (ELISA) using ABTS, as a substrate for HRP conjugate is studied. In a comparative study among 4 substrates, namely; 5-aminosalicylic acid (5AS), O-phenylenediamine (OPD), O-tolidine (OT) and ABTS, for HRP in terms of sensitivity, ABTS is the most sensitive, stable and the best in visuality by its bluish-green color[1]. ABTS is a typical peroxidase substrate. For purification and characterization peroxidase positive transformants are cultivated in large scale (XL) under conditions that yield active protein in the culture supernatant. After 160 h cultivation an activity of 55,000 U/L in relation to the substrate ABTS is achieved and the supernatant containing the peroxidase is harvested. With ABTS as substrate the peroxidase activity falls significantly when the H2O2 concentration rose above 0.125 mM, indicating that the enzyme is inhibited by H2O2. Maximum reaction rates depending upon substrate tested reache values between 31.2 and 125 μM[2].

Protocole
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].
