Next Generation Sequencing (NGS) / High-Throughput Sequencing (HTS) Services

Charles River has partnered with PathoQuest, a genomics expert, to bring pharmaceutical and biotech companies NGS services.

Applications for NGS

  • Viral Safety

    Adventitious viruses can contaminate biopharmaceutical production systems and go undetected with consequent risks to the final product. NGS testing is a technique that does not require targeted primers to look for viral contamination; instead it is able to scan millions of RNA/DNA sequences concurrently. After sequences of interest are identified, bioinformatics are used to scan through them to determine matches to known viruses and, potentially, to identify new, unknown viruses. Confirmation testing for NGS “hits” can then be done via targeted PCR approaches.

    Our NGS-based adventitious virus testing approach uses a process called metagenomics to provide a more sensitive and comprehensive method to the identification of pathogens.

    Our advanced approach permits the identification of pathogens from production samples such as:

    • Vaccine & virus stocks
    • Eukaryote cell banks
    • Prokaryote cell banks
    • API & raw materials
    • Investigational materials
  • Genetic Stability Testing/Cell Line Characterization

    NGS permits parallel sequencing of millions of DNA fragments and is now recognized as one of the most powerful and reliable tools for full genome sequencing. The combination of PathoQuest’s expertise in microbiology and virology combined with Illumina’s state-of-the-art NGS sequencing platforms makes us a unique solution provider for your studies on cell lines and virus stocks when looking at cell line identity and/or purity (monoclonality) evaluation.

    We offer sequencing on Nanopore MinIon, MiSeq, or NextSeq of STR (single tandem repeat) for DNA fingerprinting, insert, or targeted sequences comparison. For full genome sequencing we offer services on MiSeq or NextSeq systems and de novo assembly or comparison to a reference sequence in a fast turnaround time.

    The full suite of services for cell line characterization includes:

    • Characterization of novel cell lines used in production processes (e.g., vaccines)
    • Full genome sequencing
    • Cell identification (STR)
    • Clonality testing
    • Genetic drift studies
    • Cell re-engineering

    The use of NGS for these purposes allows you to run one study instead of having to perform multiple assays to achieve the same comprehensive results.

  • De-Risking the Drug Development Pipeline

    NGS metagenomic approaches also enable the testing of all biological media and other components that are used in the development of biologics from the R&D stage to the batch release of marketed products, including investigations in the case of a contamination. By including raw material testing in your viral safety package you lower your risk of finding a contaminant later in your production processes.

Key Features of the NGS Testing Approach

  • A fully GLP-integrated service from sample preparation to actionable report, including review and signature by an expert virologist or geneticist
  • Non-hypothesis driven testing
  • Robust and powerful bioinformatics tools including an automated BioIT pipeline and a secured private data center
  • Ability to identify a broad range of viruses, including still unknown viruses
  • Ability to use one comprehensive test instead of multiple assays, saving time and money
