The Genomic DNA Purification Kit uses a membrane-based system to quickly purify high-quality genomic DNA that is suitable for downstream applications such as agarose gel electrophoresis, restriction enzyme digestion, and PCR analysis. Genomic DNA can be purified from cells in as little as 20 minutes. Using a microcentrifuge, up to 20 mg of tissue (mouse tail or animal tissue) or between 1 x 10^4 to 5 x 10^6 cells can be processed per purification. NOTE: Genomic DNA purification from tissue requires overnight digestion with Proteinase K Solution (Catalog #79016) prior to purification.
