RETHINK GENETIC TOXICOLOGY

Characterize mutations in vitro and in vivo with DuplexSeqTM Mutagenesis Assays

LEARN MORE ABOUT OUR TECHNOLOGY

DuplexSeq™ mutagenesis assays offer an immediate solution for nitrosamine impurity assessment for your pharmaceutical products

Don’t wait for your in vivo mutagenicity data

Duplex Sequencing studies provide the Mutation Frequency (MF) data you need for mutagenicity testing and BMD modeling without having to wait for a TGR study.

  • Compatible with both wild-type and transgenic rodents
  • Repurpose tissues from general tox studies to assess mutagenicity
  • Gain additional data on mutation type to supplement mutation frequency

Design your study today

TwinStrand now offers mutagenicity studies for nitrosamine impurities both in-house and through select service providers.

Overcome the limitations of conventional mutagenesis assays by characterizing DNA mutations in vitro or in vivo from a wide array of samples

TwinStrand’s DuplexSeqTM Mutagenesis Assays use error-corrected NGS (ecNGS) technology to characterize DNA mutations and calculate mutational frequencies.

Flexible

  • Compatible with in vivo and in vitro studies
  • Kits for human, mouse, and rat samples
  • Compatible with any cell type and tissue

Comprehensive

  • Directly detect and quantify mutation frequency
  • Characterize mutation spectra and signatures
  • Gain insight into mutagenic mechanisms

Powerful

  • Eliminates the need for transgenic rodent models
  • Streamline nitrosamine impurities testing
  • Consistent, repeatable readouts across sample types
