Magnetic-bead nucleic acid extraction uses paramagnetic particles to bind DNA or RNA, then separates nucleic acids from contaminants with washes before elution.
Typical automated workflow
- Binding — sample lysate mixes with beads in plate wells.
- Washing — magnets collect beads while wash buffers remove inhibitors.
- Elution — purified nucleic acid releases into a final volume for downstream assays.
MultiEX systems automate these stages with programmable mixing, heating, and timing per kit protocol.
Open-system kits
MultiEX instruments are positioned as open-system — you must confirm kit IFU compatibility for your sample type and matrix. Avoid assuming universal kit support.
Instrument fit
See the magnetic bead DNA extraction system guide and MultiEX 032 for mid-throughput specs.
