This kit is suitable for the rapid extraction of high-purity viral DNA/RNA from samples such as nasopharyngeal swabs, environmental swabs, cell culture supernatants, and tissue homogenate supernatants. The kit is based on silica membrane purification technology that eliminates the need for using phenol/chloroform organic solvents or time-consuming alcohol precipitation to extract viral DNA/RNA of high quality. The nucleic acids obtained are free of impurities and ready for use in downstream experiments such as reverse transcription, PCR, RT-PCR, real-time PCR, next-generation sequencing (NGS), and Northern blot.
