From: Protective effect of Pterostilbene against free radical mediated oxidative damage
A. Gel electrophoresis pattern of pBR322 plasmid DNA after induction of oxidative damage in the presence of different concentrations of Pterostilbene. Lane 1-Undamaged DNA; Lane 2- Damaged DNA in presence of hydroxyl radical; Lane 3-DNA in presence of Pterostilbene alone; Lanes 4-7- oxidatively damaged DNA in presence of 0.05, 0.10, 0.15 and 0.20 mM Pterostilbene, respectively. B. Densitogram analysis of electrophoreogram to quantitate supercoiled and nicked circular DNA. Values are expressed as mean ± SE. Dissimilar alphabets in superscript indicate significant difference at p< 0.05.
