DNA protection assay of endophytic fungal extracts. Calf thymus DNA (5 μg) was incubated with Fenton’s reagent and the endophytic fungal extracts (150 μg/ml). After the incubation at 37 °C for 30 min, the mixture was run through agarose gel (1%) electrophoresis. The results were documented using XR+ Molecular Imager Gel documentation system (Bio-Rad, USA).
