Long-read sequencing A major advantage of nanopore sequencing is the ability to produce ultra-long reads, and over 2 Mb read lengths have been achieved. This nanopore sequencer can sequence an ultra‐long read limited by the input nucleotide length, or can determine DNA/RNA modifications. A nanopore based sequencing chip may be used for DNA sequencing. The data, presented in a graph affectionately known as a “wiggle plot,” depicted how an electrical current had changed over time as a DNA strand rapidly traversed a bacterial channel. When nanopore sequencing technology was new, it was called a “wild idea” and almost dismissed as unworkable. Traditional spreadsheet-based data capture is slow, error-prone, and creates information silos that can limit knowledge retrieval. A newer product, the Flongle, is an adapter for the MinION or GridION that makes these instruments quicker and more accessible for smaller tests and experiments. He tells GEN that he can see a day when “all nanopore sequencing will use this approach for DNA and RNA sequencing projects.”. The method can differentiate between the presence of the virus and errors that can occur during amplification—a source of false-positive results. Lastly, Schatz notes that they are currently working toward extending the approach to cDNA and direct RNA sequencing to allow for the selective sequencing of transcripts. Historically, although ONT’s reads have led the way in length, they have lagged in accuracy.
