Abstract
We demonstrate that gDNA can be conveniently and efficiently isolated and purified using standard agarose gel electrophoresis, band excision and gel purification. This method yields a substantial amount at microgram levels of gDNA per gel cleanup with high purity. An RNase A treatment step can be omitted. The quality of gDNA is suitable for next-generation sequencing, resulting in >10 Mb reads and high-quality read data (Phred score >28 up to 100 of 150 base reads). Furthermore, the gDNA can be kept intact in a gel slice for several days. This method has been tested for dictyostelids, bacteria and plants.
