Each mitochondrion contains 2 to 10 copies of mtDNA, and each cell contains numerous mitochondria.
PBMC and subcutaneous fat contained 409±148 and 2042±391 copies of mtDNA per cell, respectively.
The assay is specific and can detect down to six copies of mtDNA, making it suitable for single-cell analyses.
Mitochondrions contain multiple copies of mtDNA genomes.
Most eukaryotic cells contain hundreds of mitochondria which harbor numerous copies of mtDNA [5], [6].
In heteroplasmy there is a mixture of normal and mutant copies of mtDNA.
Because mitochondria are typically thought to contain ∼10 copies of mtDNA, approximately 10% of all mitochondria might have replicating mtDNA.
Numts are non-functional copies of mtDNA in the nucleus that have been found in major clades of eukaryotic organisms, e.g., arthropods [134], [137], crustaceans [136] and decapods [135], [138], [139].
We carried out 44 PCR amplifications using as template the same amount of DNA as used in the ancient DNA amplification i.e. approximately 5,000 6,000 copies of mtDNA per reaction tube.
In preliminary experiments, we have demonstrated that 2',3'-dideoxycytidine (ddC) depletes porcine oocytes of 95% of their original mtDNA content during 42 hours of IVM, which results in 20160±4625 copies of mtDNA persisting [29].
The peak level was at 0.14±0.055% (mean±SEM) in 2-cell embryos, representing 243 copies of mtDNA whilst the lowest level was in blastocysts (P<0.001; Figure 3).
