Precise determination of mitochondrial DNA copy number in human skeletal and cardiac muscle by a PCR‐based assay: lack of change of copy number with age

Deletions in mitochondrial DNA (mtDNA) accumulate with age in humans without overt mitochondriopathies, but relatively limited attention has been devoted to the measurement of the total number of mtDNA molecules per cell during ageing. We have developed a precise assay that determines mtDNA levels r...
