Sequence confirmation of synthetic DNA exceeding 100 nucleotides using restriction enzyme mediated digestion combined with high-resolution tandem mass spectrometry
Great success for our analytical research department! In a highly acclaimed scientific paper, Dr. Michael Rühl and his team have described a new method developed in-house for the difficult challenge of sequencing long oligonucleotides. This means that even large DNA molecules can now be prepared in such a way that their sequence can be confirmed using mass spectrometry, increasing the sequence coverage of the oligonucleotides from approximately 15-25% to 100%.
Benefits for our clients:
- Increased sequence coverage: up to 100% sequence coverage for long oligonucleotides, ensuring thorough verification
- Enhanced quality control: robust method for quality control in regulated environments, crucial for drug development
- Reliability: reliable technique for confirming sequences of synthetic DNA, aiding the development of therapeutic oligonucleotides
- Versatility: applicable to range of DNA molecules, supporting various research and development needs
- Regulatory compliance: aligns with stringent regulatory standards
Introduction:
The importance of oligonucleotide therapeutics, such as antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs), has grown significantly, particularly for treating inherited diseases. Technologies like CRISPR-Cas9 have also highlighted the need for accurate DNA sequencing. While mass spectrometry (MS) is a standard method for analyzing RNA therapeutics, its application to long DNA molecules has been limited due to the challenges in sequencing accuracy beyond 60 nucleotides.
Methodology:
We developed a method that combines restriction enzyme digestion with high-resolution tandem mass spectrometry. The process begins with the use of common restriction enzymes to create specific digestion products from DNA molecules. These products are then analyzed using ion pair reverse phase chromatography coupled to a time-of-flight mass spectrometer. This setup allows for collision-induced dissociation (CID) for sequence analysis.
Results:
The study demonstrated that using restriction enzymes significantly increased sequence coverage from 23.3% (using direct CID-MS/MS) to 100%. The approach involved generating partial duplexes with enzyme-directing oligonucleotides, enabling site-specific cleavage by the restriction enzymes. The resulting smaller DNA fragments were easier to analyze, allowing for complete sequence verification. This method was successfully applied to single-stranded DNA molecules and a double-stranded 131 base pair DNA duplex, confirming the sequences with high accuracy.
Discussion:
We highlight the method's applicability for research, development, and quality control in regulated environments. This approach is especially valuable for confirming the sequences of synthetic DNA molecules used in therapeutics. The study notes that while traditional methods like Sanger sequencing and next-generation sequencing (NGS) are widely used, they often cannot confirm the sequence of the target molecule directly or detect certain modifications. The restriction enzyme mediated approach provides an additional layer of sequence confirmation, ensuring the highest standards of accuracy.
Conclusion:
This novel method offers a reliable and efficient solution for confirming the sequences of long synthetic DNA molecules, crucial for the development of DNA-based therapeutics. The approach's ability to provide 100% sequence coverage and its suitability for quality control makes it a valuable tool in the pharmaceutical industry. Future work may explore the applicability of this method to synthetic DNA with chemical modifications and other complex DNA structures, further enhancing its utility in genetic research and therapeutic development.
