NGS Services for Biologics

OverviewBiologicsSample RequirementsViral Vector Analysis DeliverablesApplicationsFAQ

Overview

Next-Generation Sequencing (NGS) has emerged as a critical, ultra-sensitive analytical tool for the molecular characterization, viral safety assessment, and quality control of modern biopharmaceutical products. By replacing or complementing traditional in vivo and in vitro assays, NGS provides unmatched resolution for establishing product purity and regulatory compliance.

Our biologics-focused NGS services seamlessly integrate high-sensitivity sequencing architectures with highly curated bioinformatics workflows. Engineered to meet the stringent demands of bioprocess development, we support impurity identification, viral vector stability profiling, genomic integrity verification, and IND/BLA-enabling regulatory research.

We partner with biopharmaceutical sponsors globally, providing robust sequencing solutions across complex biological matrices—ranging from viral vectors and advanced vaccines to cell therapies and recombinant proteins.

Biologics We Support

We support sequencing-based characterization and safety assessment for diverse biologics modalities throughout research, process development, and product evaluation workflows.

Monoclonal Antibodies

Support for residual nucleic acid assessment, contaminant investigation, and manufacturing-related characterization studies.

Viral Vectors

Comprehensive sequencing solutions for AAV, lentiviral, and other gene delivery systems.

Vaccines

NGS-based analysis for viral characterization, identity confirmation, and safety evaluation.

Exosomes

Profiling of exosome-associated RNA, DNA, and other nucleic acid cargo to support product characterization studies.

mRNA Therapeutics

Sequence verification and integrity analysis for mRNA-based therapeutic products.

Cell Therapy Products

Genomic characterization, vector-related analysis, and viral safety assessment for engineered cell therapy products.

Sample Requirements & QC

Supported Sample Types

  • Purified biologics
  • Viral suspensions
  • Cell culture supernatants
  • Cell substrates
  • Serum and raw materials
  • Nucleic acid samples

Sample Quality Requirements

Samples should meet project-specific concentration, purity, and storage requirements to ensure sequencing performance and da ta reliability.

Viral Vector Characterization & Biosafety Evaluation

In alignment with current industry trends and ICH Q5A (R2) guidelines, we offer two standardized pipelines integrating high-sensitivity sequencing with validated bioinformatics.

Pipeline 1: Advanced Viral Vector Characterization

Focused on quality control and molecular profiling for cell and gene therapy (CGT) products:

  • Full-Length Genome Sequencing: Achieves complete mapping across complex regions, including AAV Inverted Terminal Repeats (ITRs).
  • Genome Integrity Assessment: Quantifies full vs. empty/partial capsids and detects truncated vector genomes.
  • Structural Variant Detection: Identifies unintended insertions, deletions, or target plasmid backbone carryover.

Pipeline 2: Biosafety Testing & Adventitious Agent Detection

An unbiased alternative to traditional assays for contamination screening in cell banks and raw materials:

  • Host Background Depletion: Digitally filters host cell noise to maximize detection sensitivity for low-level signals.
  • Metagenomic Contaminant Identification: Classifies viral, bacterial, and fungal reads against curated repositories to capture known and novel pathogens.
  • Genetic Stability Monitoring: Tracks batch-to-batch genetic drift and single nucleotide variants (SNVs) against your reference sequence.

NGS Applications for Biologics

Our NGS techniques enable biologics research, process development and safety assessment with integrated sequencing and bioinformatics analysis.

  • Adventitious Agent Detection: Sensitive screening for known and unknown viral contamination in biologicals, cell substrates and raw materials.
  • Residual Host Cell DNA Analysis: Identification and characterization of host generated nucleic acid contamination from industrial systems.
  • Metagenomic Pathogen Screening: Exploratory safety assessment in complicated biological material using comprehensive microbial and viral profiling.
  • Genetic Stability Testing: Evaluation for genomic integrity, sequence consistency and batch-to-batch variability.
  • Product Characterization: Sequence confirmation and molecular profiling for identity and quality assessment of biologics.
  • Integration Site Analysis: Characterization of integration patterns and insertion sites of lentiviral and other integrating vector systems.

FAQ

What types of biologics samples can be analyzed?

We support viral vectors, vaccines, monoclonal antibodies, exosomes, cell therapy products, sera, and other biologics-related materials.

Can NGS detect completely unknown or novel viral contaminants?

Yes. Because our metagenomic workflows do not rely on organism-specific primers, they can capture and identify novel, divergent, or unexpected viral sequences by cross-referencing translated amino acid databases.

Do you support viral vector sequencing projects?

Yes. We provide sequencing and integrity analysis for AAV, lentiviral, and other viral vector systems.

Do you provide bioinformatics analysis?

Yes. Integrated bioinformatics analysis and customized reporting are included in our workflows.

Can your workflows support regulatory research?

Our workflows are designed to support research and safety assessment applications with standardized sequencing and data analysis strategies.

Can low-input or complex biologics samples be analyzed?

Yes. Sequencing strategies can be optimized for challenging sample types, including low-input materials, viral preparations, and complex biological matrices.
