Generate pure genomic DNA, ready for shearing and library prep. Sixteen micrograms of genomic DNA was purified from 25 mg of mouse heart tissue using the PureGenome™ Tissue DNA Extraction kit. Lane 1: 0.1-12 kbp DNA ladder; lane 2: mouse heart genomic DNA. A260/A280 ratio was 1.8. B. DNA shown in (A) was used to generate an Illumina sequence-compatible NGS library; DNA was first sheared using a Covaris® S220 Ultrasonicator to an average size of 200 bp (red trace). Two microgram of the sheared DNA was used to generate the NGS library using the PureGenome™ NGS Library Preparation Reagents (blue trace). Click image to enlarge.
