  • Clinical Tumor Tissue Evaluated with Illumina® TruSight™ Oncology 500 (NGS) Assay and Sheared on the Covaris ML230 Focused-ultrasonicator

    Application Notes
    Abstract: DNA fragmentation is a critical step in the preparation of high-quality next generation sequencing (NGS) libraries. Covaris Adaptive Focused Acoustics® (AFA®) technology guarantees highly reproducible fragmentation of nucleic acids, which is especially relevant while working with valuable clinical samples for pan-cancer NGS assays such as the Illumina®’s TruSight™ Oncology 500 (TSO 500) panel. This panel was developed jointly by Illumina® and Covaris to provide high quality sequencing results. The DNA fragmentation protocol was previously released for the Covaris E220evolution, LE220-plus, and ME220 Focused-ultrasonicators [1]. In this application note, we present the ML230 and microTUBE-50 protocol to shear DNA to a fragment distribution optimized for the TSO 500 panel.

  • Tumor Tissue Evaluation with the Illumina® TruSight™ Oncology 500 (NGS) Assay using the Covaris R230 Focused-ultrasonicator for Clinical Research Studies

    Application Notes
    Abstract: Next-generation sequencing (NGS) library preparation workflows comprise DNA fragmentation as an essential step. Covaris’ Adaptive Focused Acoustics® (AFA®) Technology enables precise and high-quality data from NGS workflows by ensuring efficient, reliable, and reproducible nucleic acid fragmentation. Efficient DNA shearing is particularly important when working with precious clinical research samples for Comprehensive Cancer Profiling (CCP) using pan-cancer NGS assays such as Illumina’s TruSight Oncology 500 (TSO 500) panel. The DNA fragmentation protocol for the TSO 500 panel was initially released for the Covaris Focused-ultrasonicators ME220, E220evolution, LE220, and ML230 (1,2).In this application note, we present a DNA fragmentation protocol with the R230 Focused-ultrasonicator using 96 microTUBE plates to achieve the optimal fragment size for the TSO 500 panel. A comparative sequencing analysis between samples sheared with the Illumina-validated protocol on the LE220 focused-ultrasonicator and those sheared using the Covaris developed protocol on the R230 showed equivalent or better results for samples sheared on the R230, while decreasing the sample processing time by ~30%. The results in this application note highlight that the automatable R230 enables efficient, high-throughput workflows with Covaris AFA Technology resulting in the robust, reproducible, and confident fragmentation needed for comprehensive pan-cancer panels such as Illumina´s TruSight Oncology 500 assay.

    Mechanical Fragmentation of RNA using the Covaris Adaptive Focused Acoustics® (AFA®) Technology for Development of mRNA-based Vaccine and Gene Therapy Platforms
    Introduction The emergence of Next-Generation Sequencing (NGS) technologies has greatly contributed to targeted gene discovery for the generation of new mRNA-based vaccines and therapeutics [1,2]. With the advancement in the world of NGS technologies, RNA sequencing (RNA-Seq) has rapidly become the method of choice for analyzing the transcriptomes of disease states [3], of biological processes, and across a wide range of clinical study designs. Synthetic mRNA has been considered an emerging biotherapeutic agent for decades [4]. However, the outbreak of the COVID-19 pandemic promoted the application of mRNA technologies in development of SARS-CoV-2 vaccines, and there has been a huge increase in interest in the research and development of mRNA-based vaccines [5]. Despite the tremendous improvement in RNA-based NGS technologies, the mRNA-based sequencing methods still present some unique challenges in production, characterization, and quality controls, especially when compared to their traditional protein-based counterparts. One critical challenge is obtaining products that are of homogeneous sequence. In this regard, NGS has proved to be a key tool to probe and address this challenge. This study, conducted in collaboration with GreenLight Biosciences, presents a mechanical mRNA fragmentation methodology that uses Covaris’ Adaptive Focused Acoustics (AFA) Technology to generate the right-sized population pivotal for successful Illumina® library preparation and reproducible sequencing data.Download PDF
