This kit is suitable for the rapid extraction of genomic DNA from plant tissues, especially those rich in polysaccharides and polyphenols. The kit is based on silica gel membrane purification technology without time-consuming alcohol precipitation and does not require phenol/chloroform, or any other toxic reagent during the extraction process, which can effectively remove impurities and other organic compounds from plant cell. The obtained DNA with high purity and stable quality can be directly used in PCR, qPCR and enzyme digestion, etc. The amount of DNA extracted from different plant tissues will vary.
