Measuring mitochondrial reactive oxygen species.
This article examines recent methods for measuring reactive oxygen species produced in isolated mitochondria and within live cells, with particular emphasis on the detection of hydrogen peroxide. Protocols for reliable measurements of mitochondrial hydrogen peroxide are presented, while the advantages and pitfalls of these and other methods are discussed. New developments in the detection of lipid peroxidation are outlined. Advice is also provided to aid the interpretation of cellular data with respect to the contribution of oxygen radical production by different components of the mitochondrial respiratory chain.
