A new assay has been developed to measure mitochondrial ATP synthesis of cultured mammalian cells. Cells in a microplate are exposed to streptolysin O to make plasma membranes permeable without damaging mitochondrial function and ATP synthesis is monitored by luciferase. Addition of inhibitors of FoF1-ATP synthase (FoF1), respiratory chain, TCA cycle and ATP/ADP translocator, as well as knockdown of β-subunit of FoF1, resulted in loss of ATP synthesis. Compared with the conventional procedures that need mitochondria fractionation and detergent, this assay is simple, sensitive and suitable for high-throughput analysis of genes and drugs that could affect mitochondrial functional integrity as represented by ATP synthesis activity.
Research highlights
► A sensitive, simple assay for mitochondrial ATP synthesis that represents mitochondrial functional integrity.
► It needs no detergent and no mitochondrial fractionation.
► Good for high-throughput analysis of mammalian cells cultured on a microplate.
