Automated NGS Procedure
Size Fractionation with MagSi-NGSPREP

Gel electrophoresis of DNA ladder at different reagent:sample volume ratios.
The size of fragments eluted from the beads (or that bind in the first place) is determined by the end concentration of MagSi-NGSPREP, and this in turn is determined by the mix of DNA and beads.
A 50 µl DNA sample plus 75 µl of beads will give a MagSi-NGSPREP:DNA ratio of 1.5. As this ratio is changed, the length of fragments binding and/or left in solution also changes. Hence, the lower the ratio of MagSi-NGSPREP:DNA the larger the final fragments will be at elution.
Smaller fragments are retained in the buffer so you can get different size ranges from a single sample with multiple purifications. Part of the reason for this effect is that DNA fragment size affects the total charge per molecule with larger DNAs having larger charges; this promotes their electrostatic interaction with the beads and displaces smaller DNA fragments.

  • MagSi-NGSPREP is designed for an optimized purification of next generation library preparation through efficient clean up of the successive enzymatic reactions (i.e. end repair, dA-tailing, adaptor ligation). MagSi-NGSPREP is used for clean-up of library targeting sequencers such as Life Technologies’ ABI SOLiD, Ion Torrent; Illumina’s HiSeq 2000, MiSeq, GAIIx; and Roche’s 454.
  • Magnetic bead based MagSi-NGSPREP offers an efficient solution for clean-up and size selection in library preparation of NGS sequencing reactions. The simple and flexible protocol can be adjusted to your specific application and NGS platform. MagSi-NGSPREP can be used manually but is also easy to automate for high-throughput processing. In conclusion: a simple and quick way to consistent NGS results.
