With a high-profile announcement in early August, ONT signaled its determination to make an impact in the diagnostics of COVID-19 as the pandemic pushed academic scientists and companies to innovate at extraordinary speeds. Miga and colleagues were motivated to establish the T2T consortium by asking, “Can high-coverage ultra-long sequencing resolve complete assemblies of the human genome?”. For example, an array of one million cells may include 1000 rows by 1000 columns of cells. Albert Vilella, PhD, a bioinformatics consultant, tells GEN that the ability to do a $100 experiment with the Flongle flowcell, something ONT has pointed at in their recent updates, would be a “game changer” and, he expects, would lead to increased adoption of ONT’s technology. During a typical sequencing run, explains Michael Schatz, PhD, associate professor of computer science and biology at Johns Hopkins University, the data can be redundant or from irrelevant regions of the genome. Nanopore sequencing is already cheaper to access; it's competitive on a "cost per base" metric using the latest machine. LamPORE is the marriage of two processes, loop-mediated isothermal amplification (LAMP) and nanopore sequencing. This nanopore sequencer can sequence an ultra‐long read limited by the input nucleotide length, or can determine DNA/RNA modifications. Traditional spreadsheet-based data capture is slow, error-prone, and creates information silos that can limit knowledge retrieval. It wasn’t until February 2012, at the premier AGBT (Advances in Genome Biology and Technology) conference in Marco Island, FL, that Clive Brown, ONT’s chief technology officer, previewed the MinION, in a talk entitled, “Single Molecule ‘Strand’ Sequencing Using Protein Nanopores and Scalable Electronic Devices.” Brown had previously worked at Solexa, the British next-generation sequencing (NGS) company acquired by Illumina in 2007. I have used this flow cell for 6 hours for the phage lambda control. And it allows for dynamic changes during the process, by controlling pore voltages in real time.
