Abstract
A magnetic bead based nucleic acid extraction system includes a plurality of magnetic beads and an alcohol-free buffer system. The alcohol-free buffer system includes a lysis binding buffer, a first wash buffer, a second wash buffer, and an elution buffer that are stable in storage at room temperature. The buffers include a special selection of chaotropic salt, detergent, precipitant and other necessary components for ideal extraction of nucleic acids. The magnetic bead based nucleic acid extraction system is stable, user-friendly and environment-friendly, efficient and efficacious nucleic acid extraction system optimal for pathogens from swab samples, and can achieve efficient both DNA and RNA extractions, be it separately or simultaneously, from both virus and bacteria in swab samples.
