Service Description

Dovetail™ Scaffolding Projects enhance your current assembly. In our state-of-the-art facility, we will work with your current input to improve order, orientation, and contiguity. Moving from library creation through HiRise™ Scaffolding with proven quality techniques we will help you unlock the potential of your genome.

  • Dovetail™ library construction and sequencing with our proprietary Dovetail™ Omni-C™ Technology
  • Assembly informatics through scaffolding with our cutting-edge assembly pipeline and genome TAD analysis, if applicable
  • Tailored approach to scaffolding using proven methodologies
  • Designated Scientific Project Manager to answer questions and provide project guidance
  • Usable genome assembly within 10 weeks
  • Highly accurate results that have been validated by multiple technology types
  • Access to Dovetail Genomics proprietary service offerings and expertise

Dovetail™ Omni-C™ Technology incorporates a sequence-independent endonuclease approach to chromatin fragmentation in the proximity ligation protocol.

The HiRise™ Scaffolding Pipeline uses the de novo assembly as an input. Multiple iterations are completed layering the use of the library sequencing data to provide a contiguous high-quality assembly.

When available, TAD analysis uses the data collected for the assembly creation to provide a view into chromatin 3D architecture, including topologically associated domains.
