A new and improved ‘gold standard’ for complete plasmid verification

Knowledge Exchange overview

During this Knowledge Exchange, three presenters from Oxford Nanopore Technologies shared a comprehensive overview of the workflow for rapid, cost-effective sequencing of complete plasmid constructs.


Aaron began by introducing why the field is moving towards routine whole plasmid verification, and how the Oxford Nanopore workflow enables any lab to implement a new and improved plasmid sequencing solution. Jemma then walked attendees through the protocol for plasmid sequencing using Oxford Nanopore Rapid Barcoding Kits. Followed by Stephen, who introduced EPI2ME bioinformatics and covered democratising data analyses for non-bioinformaticians.

The benefits of plasmid sequencing

Viewers learnt how to implement this end-to-end workflow to characterise the sequence of entire plasmid constructs rapidly, locally and at a competitive price. This enabled several advantages over other methods. For example, users could:

•    Easily verify if the plasmid insert and backbone are free of mutations
•    Completely avoid the need for primers and complicated primer walking
•    Resolve repetitive regions, dimers and deletions
•    Work across range of plasmid/BAC sizes and complexities
•    Implement a simple end-to-end workflow with rapid turnaround time
•    Keep the process in-house or at a local institution, ensuring data remains secure
