sbeadex™ magnetic microparticles enables the automated high-throughput extraction and purification of high quality DNA preparations. A novel two step binding mechanism via an adapter allows binding of nucleic acids more specifically. Final washes with pure water deliver nucleic acids in high yield, purity and quality. sbeadex chemistry is perfectly adapted to our high-throughput extraction platform: the oKtopure™.

See how it works


  • Development of customised protocols to your requirements
  • Tailor-made extractions like modified lysis or eluation steps according to user requirements
  • Extraction speed optimisation - quicker results
  • Highly flexible batch sizes
  • No potential PCR inhibitors in final wash buffers - e.g. organic solvents, salts
  • Applicable for most popular robotic platforms (f.e. Hamilton, TECAN or KingFisher)
  • Achieve sustainable extraction with non-ethanol wash
  • Sbeadex is suitable for many different sample types including plant, blood, tissue, forensic and plasmid extractions.

The particles used in the sbeadex™ and mag™ kits are modified superparamagnetic particles, which allow efficient and high quality purification of small and large DNA fragments. These allow efficient and high quality purification of small and large nucleic acid fragments of several sample materials. The beads are attracted by strong permanent magnets, but they do not become permanent magnets.

Parameters of the magnetic particles:

Colour Dark brown
Size < 53 µm, 80% 5-10 µm
Shape irregular
Specific weight 3.0 – 3.5 g / 10 mL dry particles
Maximum capacity 2 µg DNA / mg particles
Storage/stability > 2 years as dry powder at room temperature (normally the beads are delivered as suspension which is stable approx. 6 months)

LGC developed standard protocols on a broad variety of robotic platforms for extractions of all major plant species, plant samples and other sample matrices. As protocols on the KingFisher platform can easily be transferred and installed, we provide application notes based on our sbeadex standard chemistry. For all other robotic platforms and sample material not mentioned, please contact us. The extractions team is very experienced with a wide range of sample matrices, having worked with all kinds of samples in our DNA extraction service laboratories. We are able to send you DNA extraction protocols for many sample types that are not mentioned here.
