This product is intended for the extraction of genomic DNA from 1 - 20 mg of animal tissues and less than 5 × 106 cultured cells. This kit is based on silica gel column purification technology that eliminates the need for extraction using phenol/chloroform organic solvents or time-consuming alcohol precipitation. The whole extraction process takes only 30 - 60 min. The obtained DNA is ready for use in enzyme digestion, PCR, library preparation, virus DNA detection, etc.
