The protein concentration was determined by the Bradford method using BSA as a standard. The cell homogenate was mixed and incubated with 0.8 mM l-Dopa for 1 h at 37 °C and then the activity was assayed at 475 nm using ELISA micro plate reader.

    • 14 Superoxide radicals were generated in 1 ml 20 mM Tris-HCl buffer pH 8.0 containing 0.05 mM nitroblue tetrazolium (NBT), 0.01 mM phenazine methosulfate (PMS) and test compounds were preincubated for 2 min. The reaction was initiated by the addition of 0.078 mM NADH. Blue chromogen, formed due to NBT reduction, was read at 560 nm.
