Abstract This study investigates a custom 2Mb xGen Hyb panel designed against mutated gene targets implicated in several cancers using an end-to-end assay workflow on the Biomek NGeniuS platform. Automation in laboratories is advantageous to generate reproducible next generation sequencing (NGS) sample libraries, however, assay automation differs from instrument vendor to vendor but also from lab to lab with different deck layouts of the same instrument. These differences require a significant amount of optimization to design the workflow and begin generating NGS libraries. In addition to this optimization, some research, e.g., cancer research utilizes low input and/or degraded samples such as cfDNA from plasma or FFPE biopsies. Integrated DNA Technologies (IDT) and Beckman Coulter - Life Sciences together provide a walk away NGS automation solution for these research samples directly upon instrument installation with no optimization required by combining Beckman Coulter’s Biomek NGeniuS with IDT’s xGen cfDNA & FFPE DNA Library Prep kit and xGen Hybridization Capture. This trio provides a solution for laboratories to minimize technician hands-on time, error reduction, and rework while improving flexibility. IDT’s xGen cfDNA & FFPE DNA Library Prep kit utilizes novel chemistry to maximize sample input conversion, suppress adapter-dimer formation, and facilitate consensus analysis. IDT’s xGen Hybridization Capture products maintain high library diversity, obtain high on-target, and provide consistent and uniform sequencing coverage regardless of panel size. We demonstrate performance of this complete workflow with a custom 2Mb xGen Hyb panel yielding high library complexity, high on-target coverage, and capture uniformity. The combination of IDT’s xGen library preparation solutions on the NGeniuS Biomek platform provides a reliable and consistent solution that can be instantly downloaded from the portal straight to analysis of precious low input and degraded samples.
