Abstract

Standard methods for mitochondrial DNA (mtDNA) extraction do not provide the level of enrichment for mtDNA sufficient for direct sequencing and must be followed by long-range-PCR amplification, which can bias the sequencing results. Here, we describe a fast, cost-effective, and reliable method for preparation of mtDNA enriched samples from eukaryotic cells ready for direct sequencing. Our protocol utilizes a conventional miniprep kit, paramagnetic bead-based purification, and an optional, limited PCR amplification of mtDNA. Te first two steps alone provide more than 2000-fold enrichment for mtDNA when compared with total cellular DNA (~200-fold in comparison with current commercially available kits) as demonstrated by real-time PCR. Te percentage of sequencing reads aligned to mtDNA was about 22% for non-amplified samples and greater than 99% for samples subjected to 10 cycles of long-range-PCR with mtDNA specific primers.
