We investigated the effects of ischemia on the kinetics and control of mitochondria isolated from normal and ischemic heart. The dependence of the respiratory chain, phosphorylation system and proton leak on the mitochondrial membrane potential were measured in mitochondria from

Membrane potential across the plasma membrane (psi) of human sperm was determined by measuring the accumulation of triphenylmethylphosphonium (TPMP+). Washed sperm of fertile or infertile men were suspended, incubated in low-K+ and high-Na+ or high-K+ and low-Na+ medium, and allowed

The plasma-membrane potential (Delta(psi)p) in bloodstream forms of Trypanosoma brucei was studied using several different radiolabelled probes: 86Rb+ and [14C]SCN- were used to report Delta(psi)p directly because they distribute in easily measured quantities across the plasma membrane only, and [3H]methyltriphenylphosphonium

Mitochondrial dysfunction causes or exacerbates a number of diseases. These include genetic disorders such as Friedreich's ataxia where the primary lesion is a defect in a nuclear gene and those diseases caused by mutations to mitochondrial DNA. Mitochondrial damage also

Lipophilic monocations can pass through phospholipid bilayers and accumulate in negatively-charged compartments such as the mitochondrial matrix, driven by the membrane potential. This property is used to visualize mitochondria, to deliver therapeutic molecules to mitochondria and to measure the membrane
