Automated Liquid Handling for
Next-Generation Sequencing Library Preparation

Next-Generation Sequencing (NGS) or massively parallel sequencing has facilitated the integration of sequencing applications in biological research as it offers flexibility, robustness, and high throughput. A typical NGS workflow involves four key steps: sample preparation, library preparation, sequencing, and data analysis.

Library preparation is a critical process that sets the foundation of reliable sequencing data by converting the nucleic acid into a sequence-ready format. The process includes DNA fragmentation, adapter ligation, PCR amplification, purification, quantification, and normalization. If multiple samples are to be sequenced in a single run, individual libraries are indexed and pooled together. To ensure data integrity, this multi-step process demands precise liquid handling and meticulous attention to detail. Therefore, factors such as precision in pipetting volumes, protocol complexity, reaction miniaturization, processing time, and throughput level should be considered while selecting a liquid handling approach.

NGS workflow

General steps of a typical NGS workflow. Sample preparation may include an additional step of cDNA synthesis for RNA samples prior to library preparation

Library preparation with manual liquid handling is time-inefficient, labor-intensive, and constrained by limited throughput. Moreover, it becomes challenging to miniaturize the reaction using hand-held pipettes as these are prone to errors, leading to inconsistent results. Automating the NGS library preparation effectively addresses these challenges by providing precise and consistent dispensing to execute complex protocols, particularly for small volumes, thereby cutting the processing costs through miniaturization.

Formulatrix Automated Liquid Handling for NGS Library Preparation

Formulatrix automated liquid handling (ALH) offers accurate low-volume transfers for miniaturized reactions, while saving time and cost. Our portfolio consists of non-contact liquid dispensers including the Mantis® and the Tempest®, alongside the liquid handlers, the F.A.S.T.TM and the FLO i8® to enhance the library preparation efficiency with high throughput.

 

Mantis and Tempest, the tipless liquid dispensers by Formulatrix, use patented microfluidic technology for dispensing volumes in sub µL range with high precision. The F.A.S.T. (Flow Axial Seal Tip) is a 96-channel, positive displacement liquid handler which offers volume ranges from 0.1 to 13 µL. The Flo i8, an air displacement liquid handler with 8 independent spanning channels and is well-suited for higher volume transfers. The channels are integrated with flow rate sensors for real-time liquid class optimization.

 

This range of ALH technologies not only ensures precise and reproducible dispensing even for difficult reagents, but also reduces reagent consumption and overall cost by miniaturizing the library preparation.
