Biomek Automated NGS Solutions Accelerate Genomic Research

Biomek i-Series Automated Illumina TruSeq Exome Library Prep Kit

Introduction

The Illumina TruSeq Exome Library Prep kit is a workflow to generate indexed paired-end libraries and is specially designed to work with Formalin Fixed Paraffin Embedded (FFPE) samples. Solid Phase Reversible Immobilization (SPRI) bead chemistry is utilized throughout the protocol for size selection and sample cleanup steps. The process can be laborious and error-prone and is therefore ideal for Biomek automation. Choose from low to high throughput Biomek liquid handling workstations to automate all steps of the workflow providing the option for a complete walk-away solution. The methods are proven to deliver sequence- ready libraries through demonstrated performance using scientifically relevant samples. These ready-to-implement methods are compatible with Illumina TruSeq Exome Library Preparation kits (Illumina P/N FC-150-001, FC-150-002 or FC-150-003).

This application is automated on multiple Biomek workstations and provides:

  • Standardized workflow for improved results
  • Reduction in costly errors
  • Reduced hands-on-time and increased throughput
  • Quick implementation with ready-to-implement methods available delivered by knowledgeable support teams

Demonstrated Method Interface (DMI)

Three simple modules that provide the user full instructions to better ensure error-free method setup and provides users maximum flexibility for scheduling their day.

1. Biomek Method Launcher (BML) — secure interface for selecting methods without affecting method integrity and manual control.

Figure 2. Biomek Method Launcher provided an easy interface to start the method.

Experimental Design and Results

DNA was extracted from FFPE samples using FormaPure DNA Extraction Kit from Beckman Coulter.
Horizon Quantitative Multiplex Reference Standard for FFPE (HD200), breast (FFPE 76 and FFPE
96), lung (FFPE 110 and FFPE 121) and liver (FFPE 107) blocks were used to generate libraries using
Illumina’s TruSeq Exome Kit and sequenced with NextSeq. Library quality was assessed using the
Agilent TapeStation High Sensitivity D5000 kit.

Summary

The sequencing run generated 112.9M passed filter reads with 96% of those reads identified. 80% of targeted regions were covered to the a depth of at least 20X for the FFPE block samples, while over 95% of targeted regions for the Horizon sample were covered at a depth of 20X. In conclusion, Biomek I Series liquid handlers offer a flexible solution for complex NGS workflows with challenging sample types.
