What is doggybone DNA (dbDNA)?

dbDNA is a minimal, linear, covalently closed structure, which eliminates bacterial sequences. It is approved in both Europe and the US as a starting material for the production of gene therapies in Phase I, and has several advantages over pDNA including:
  • Optimal vector - Strong expression profile and eliminates bacterial sequences.
  • Amplification of complex sequences - Long sequences, GC rich sequences and sequences with secondary structure (e.g., ITRs)
  • Faster timeline to the clinic – GMP material available in a matter of weeks compared to months, removing DNA supply from your critical path.

How is dbDNA made?

With our proprietary enzymatic DNA production process, we can rapidly manufacture multiple grams of DNA using benchtop, disposable equipment.
