  • VirusMag™ One-Step DNA/RNA Isolation Kit

    VirusMag™ One-Step DNA/RNA Isolation Kit is a research-use-only (RUO) kit, which is designed for the isolation of viral DNA/RNA from the oral swab, sputum, serum, and other samples by using magnetic beads and a unique buffer system. The nucleic acid in the samples is first released by Lysis Buffer RLQP and then specifically bound on magnetic beads. The magnetic beads combined with the nucleic acid are captured by magnetic materials. Then the nucleic acid is eluted from the magnetic beads by Elution Buffer (EB).

    VSep™ Magnetic Separators

    VSep™ magnetic separators are durable and easy to use. The separators consist of a series of powerful NdFeB (neodymium-iron-boron) magnetic disks. Each magnetic disk attracts the beads in tubes fitted in an adjacent hole. VSep™ magnetic separators are widely used in cell sorting, RNA and DNA isolation, and purification of biomolecules.
