Targeted Resequencing


Retrogen offers a range of Targeted Resequencing Solutions on Illumina's MiSeq and Life Technologies’ Ion Torrent Personal Genome Machine (PGM) platforms. Recent breakthroughs in multiplexed PCR technology brought amplicon based workflows to NGS with the ability to target hundreds of unique loci throughout an entire genome at once. Incorporating an indexing strategy in your sequencing run can provide valuable information for disease, cancer, and biochemical pathways. For larger targets, a probe-based protocol can provide up to exome level enrichment. Please contact your Retrogen NGS Project Manager for assistance in configuring your project.
