Efficient, Accurate Size Selection

The ProNex® Size-Selective Purification System enables the rapid and efficient magnetic resin-based purification of double-stranded DNA (dsDNA) for next-generation sequencing (NGS), polymerase chain reaction (PCR) and general molecular biology applications. The ProNex® System allows users to select the desired size of purified dsDNA fragments, from 100bp to 750bp. The novel reagent formulation provides significantly improved selectivity, reproducibility and yield relative to traditional dsDNA purification methods. In addition, the ProNex® System can be used in both manual and automated high-throughput workflows.

ProNex Size-Selective DNA Purification System

Control Your DNA Size

By adding varying ratios of ProNex® Size Selection Chemistry to your sample, you can control what size DNA is retained or eliminated. This enables NGS library and PCR fragment cleanup, as well as dual size selection of libraries.

DNA Purification and DNA Size Selection

Superior DNA Recovery

ProNex NGS Library Prep versus AMPure DNA Recovery

Serial buffer exchange/cleanup purification comparison between ProNex® Size-Selective Purification System and AMPure® XP beads. Five sequential cleanup rounds (AMPure® XP = 1.8X ratio, ProNex® = 3X ratio) were performed on a 200bp DNA step ladder. Ratios designed to retain all fragments. N=8 replicates per sample.

Easy to Pipette with Fast Bead Response

Significantly Lower Viscosity—No Sticking to Tips

ProNex® beads (left) have significantly lower viscosity than AMPure® XP beads (right), making them far easier to pipette accurately and easily, increasing reproducibility of size selection and recovery.

5X Greater Bead Response Time—See the Difference

ProNex® beads (bottom) have a magnet response time that is ~5X faster than AMPure® XP beads (top), ensuring tighter bead pelleting and greater confidence in sample handling.

More Accurate Dual Library Size Selection

Getting the most sequencing data for your money requires precise size selection of your library. Elimination of both small and large fragments outside the desired range is critical to avoid wasting money on unusable reads. The ProNex® Size Selective Purification System not only removes more low- and high-molecular weight DNA than existing methods but also retains more of the target fragment sizes you really want.

E. coli libraries were created using the NEBNext® Ultra™ II DNA Library Prep Kit for Illumina®, using starting input values of 1,000ng, 100ng, 10ng and 1ng. Libraries were size selected with either AMPure® XP beads or the ProNex® Size-Selective Purification System. Libraries were centered at 300bp, using recommended library kit manufacturer’s recommendations for size selection with AMPure® XP beads and Promega’s guidelines for the ProNex® Size-Selective Purification System. Post-PCR libraries are shown. Libraries generated using the ProNex® System significantly reduced high-molecular weight DNA carryover and produced tighter size distribution.

Better Library Prep = The Sequencing Data You Want

ProNex® Chemistry delivers tighter distribution of desired fragment sizes with minimal fragments outside of your chosen range. A more narrow distribution means fewer wasted reads and more efficient sequencing.
