Long nucleic acids/transgene sequences in cell and gene therapies range in length from 500 to 10,000 nucleotides or more. Confirming their identity and purity is critically important to ensure the safety and efficacy of these new modalities. Waters chromatography columns and systems combined with optical detection and/or mass spectrometry provide powerful capabilities for confirming the physicochemical properties of these nucleic acids and of their fully assembled drug product; when packaged into lipid nanoparticles (LNPs), viral vectors (e.g. AAV), or virus-like-particles (VLPs) for cell delivery.

LC-UV-MS analysis of the HPRT sgRNA digested with recombinant RapiZyme Cusativin. Three independent recombinant enzyme batches of RapiZyme Cusativin were used to digest HPRT sgRNA, and the three UV chromatograms (black, blue, and red traces) are overlayed on top of each other, indicating highly reproducible digestion behavior.
