Biomek i-Series Automated AmpliSeq for Illumina® Library Prep Kit
Introduction
The AmpliSeq for Illumina Library Prep Kit is used to prepare dual indexed libraries for targeted sequencing on Illumina platforms. Sample inputs range from 2-200 ng DNA and 2-200 ng RNA and also compatible with FFPE samples thus allowing researchers to work with low input DNA and RNA.
In this flyer, we demonstrate the automated performance of AmpliSeq for Illumina Library Prep Kit on the Biomek i5 Span-8 Genomics Workstation for three of the workflows compiled in a single automated method.
- Ampliseq for Illumina Cancer Hotspot Panel v2 (for max 96 DNA samples with single DNA panel)
- Ampliseq for Illumina Comprehensive Panel v3 (for max 48 DNA and 48 RNA samples with 2 tube panel for each)
- Ampliseq for Illumina Focus Panel (for max 48 DNA and 48 RNA samples with single tube panel for each)
In comparison to the manual pipetting, the AmpliSeq for Illumina Library Prep Kit automated on Biomek platform provides:

This workflow is for Comprehensive V3 Panel
RNA and/or DNA workflow can be run independently
The method is modularly written and each process can be run independent of each other.

Automated Method
The method can be run using the interactive Guided Labware Setup software. It provides logical start and stop points assigned based on Illumina’s recommendations, enabling flexibility to the users for scheduling their workflow and allowing each laboratory to address their individual requirements for sample processing and throughput.
Application is designed to run up to 96 total samples. The instrument has 1 each Static Peltier and Orbital Shaker. Application can run DNA and RNA workflow individually or simultaneously, if applicable.

The software provides several user friendly features such as:
1. Biomek Method Launcher (BML)
BML is a secure interface for method implementation without affecting method integrity. It allows the users to remotely monitor the progress of the run. The manual control options provide the opportunity to interact with the instrument, if needed.
Figure 3. Biomek Method Launcher provides a straight-forward interface to launch the method
2. Method Options Selector (MOS)
MOS enables selection of plate processing and sample number options to maximize flexibility, adaptability and the ease of method execution.
Figure 4. AmpliSeq for Illumina Method Options Selector enables one to select DNA and/or RNA to run, batch size and other processing options.
3. Guided Labware Setup (GLS)
GLS is generated based on options selected in the MOS, and provides the user specific graphical setup instructions with reagent volume calculation and step by step instructions to prepare reagents.

Experimental Design
The AmpliSeq for Illumina Comprehensive Cancer Panel v3 was run with 10ng each of 8 DNA samples (4 replicates of Horizon™ HD 798 and 4 replicates of HD 803) and 10ng of 8 RNA samples (4 replicates of Agilent® Universal Human Reference RNA and 4 replicates of Seracare® Fusion RNA mix v3 Catalog No. 0710-0431) to generate libraries for sequencing on MiSeq. The quantity of the original sample was assessed with Qubit™ ds HS DNA Kit and Qubit™ HS RNA Kit. Libraries were normalized and pooled and After paired end 2x151 bp sequencing run, analysis was performed using the BaseSpace Sequence Hub.
Results
A robust and reliable automation solution for NGS library prep is essential to take full advantage of Illumina’s sequencing technology. Automation saves up valuable time and money and helps the researchers to obtain an efficient process with more walk-away time.
