ForenSeq DNA Signature Prep Kit

Generate more comprehensive DNA profiles for up to 96 DNA samples with fewer than two hours of hands-on time using our simple, plate-based workflow. The ForenSeq DNA Signature Prep Kit is the first next-generation sequencing (NGS)-based short-tandem repeat (STR) sequencing chemistry approved for upload to the National DNA Index System (NDIS) for casework. Combining over 200 markers, including autosomal, X- and Y-STRs, identity-informative, phenotype-informative and biogeographical ancestry-informative SNPs into a single, streamlined workflow, the kit eliminates the need to run multiple STR tests.

The ForenSeq DNA Signature Prep Kit is part of an integrated workflow that sequences libraries on the MiSeq FGx Sequencing System and analyzes data in Universal Analysis Software (UAS). Designed, developed, and manufactured as a high performance, end-to-end solution for forensic samples, the entire portfolio is backed by extensive technical support. In addition, quality-controlled manufacturing ensures reproducibility with the convenience of all-in-one library prep kits.

Key Features

  • Superior Analysis of Challenging Samples Recover more highly discriminating genetic information from heavily degraded DNA than traditional methods with a high concentration of amplicon sizes less than 200 bp.
  • Increased Resolution for Mixtures Leverage the power and sensitivity of the MiSeq FGx System to detect minor contributors at < 5% in mixed samples.
  • No Need for Multiple Kits Simultaneously interrogate your choice of markers in a single amplification. Choose from either DNA Primer Set A (DPMA) or DNA Primer Set B (DPMB) to consolidate multiple existing capillary electrophoresis (CE)-based kits.
