20150275200 | METHOD OF ISOLATING PURE MITOCHONDRIAL DNA - A method for preparing circular double stranded mitochondrial DNA (mtDNA) substantially free of genomic DNA (gDNA) comprising the steps of: providing a cellular lysate free of protein and RNA contaminants, precipitating cellular debris and proteins out of said lysate and obtaining a solution comprising purified circular double stranded mitochondrial DNA (mtDNA) and genomic DNA (gDNA), incubating said solution with an amount of Hind Exonuclease V for a time and at a temperature effective to cleave non-circular DNA and obtain circular double stranded mtDNA, incubating said circular double stranded mtDNA with an amount of Ampure beads effective to bind said circular double stranded mtDNA, washing said beads with ethanol, and eluting said mtDNA from said beads, wherein said method is free of ultra-centrifugation. | 10-01-2015 |
