Cleanup of enzymatic reactions and size selection of DNA fragments are common steps in the vast majority of NGS library preparation workflows. NucleoMag NGS Clean-up and Size Select employs scalable magnetic bead technology to enable efficient cleanup and tunable size selection of NGS libraries for an array of sequencing applications. The flexible protocol allows for single- or double-sided size selection and enrichment of fragments of a given size via adjustment of bead-to-sample volume ratios.

NucleoMag NGS Clean-up and Size Select consists of paramagnetic beads suspended in binding buffer that selectively bind DNA fragments based on the volume ratio of bead suspension to sample. After magnetic separation and removal of supernatant, the beads are washed with ethanol followed by a short drying step. Following elution in low-salt buffer or water, the highly purified DNA is free of contaminants such as nucleotides, primers, adapters, adapter dimers, enzymes, buffer additives, or salts, and can be used directly in downstream applications.

NucleoMag NGS Clean-up and Size Select provides comparable performance and employs the same dilution ratios for size selection as magnetic bead-based solutions from other providers (e.g., AMPure XP), such that it can be incorporated in existing workflows without the need for protocol adjustment or optimization.
