Post DNA shearing, the library construction process for next generation sequencing mostly requires fragment selection regardless of the platform. Obtaining high recovery post fragment selection is becoming an important contributor for the reduction of sequencing bias. The AxyPrep Mag FragmentSelect-I kit is optimized for Illumina next generation sequencing platforms and Life Technologies (SOLiD) fragment size selection needs simplifying the library construction workflows. Where as, the AxyPrep Mag FragmentSelect-R is designed for fragment size selection needs in the Roche/454’s DNA Genome sequencer library construction workflow. The AxyPrep Mag FragmentSelect kits utilize a unique paramagnetic bead technology for quick high-throughput optimized DNA size selection suitable for various next generation sequencing platforms.
