Abstract: We tested the effect of an anti-oxidant mixture on respiration in isolated rat brain mitochondria. Mitochondria were isolated in mannitol/sucrose/EGTA/BSA±SCAVEGR™ anti-oxidants (SOD, catalase, vitamin E, vitamin E acetate, and glutathione reduced). TBARS were reduced by greater than 40% with SCAVEGR. Respiration driven by ADP showed a two-fold higher Vmax and a 15% higher respiratory control ratio when mitochondria were prepared with SCAVEGR. SCAVEGR also stabilized the octameric state of mitochondrial creatine kinase and thus improved creatine-stimulated respiration. These results suggest that significant improvements in brain mitochondrial function are obtained by isolation in the presence of an anti-oxidants mixture. • Keywords: Anti-oxidant, Brain mitochondria, Creatine kinase, Respiration, ROS
