Prof Yutaka Suzuki’s lab at the University of Tokyo published a paper last week in DNA research: Sequencing and phasing cancer mutations in lung cancers using a long-read portable sequencer. In the paper they described their work detecting SNVs in EGFR, KRAS, NRAS and NF1, and EML4-ALK, […]

Iain Macaulay organised a #singlecell meeting at Norwich’s Earlham Institute earlier this month. The meeting was fun and there were some great presentations during a day of talks and discussion on the development and application of single cell technologies. 100+ #singlecell analysis methods at www.tinyurl.com/mqabyur One that […]

Update on @illumina index-swapping: better libraries

By | May 11th, 2017|Categories: Methods and applications, Next-generation sequencing|Tags: |3 Comments

Index-swapping appears to be driven by excess adapter/primer (Illumina whitepaper). The take-home messages are 1) to use UDIs (unique dual-indexes), and 2) clean-up your libraries to remove left-over adapter/primer. Later in this post I’m going to work through one solution for getting rid of any remaining adapter/primer in an NGS library; but […]

Inflection points for @nanopore sequencing

By | May 5th, 2017|Categories: Methods and applications, Nanopore sequencing, Next-generation sequencing|6 Comments

When will nanopore sequencing push short-reads (i.e. Illumina) off their pedestal? According to Clive PromethION is the Illumina killer…but this same conversation was going on many times at London Calling. I wanted to highlight two areas that might be about to flip to ONTs advantage […]

Update on @illumina index-swapping: better barcode design

By | April 24th, 2017|Categories: "Experimental design controls etc", Core facilities, Methods and applications, Next-generation sequencing|Tags: , , |2 Comments

Last week I followed up on the index-swapping issue after Illumina released their white paper and also covered what Ethan Linck at The Molecular Ecologist had posted about the Sinha et al BioRxiv paper. In that post I said I’d write a follow-up post about index design over the weekend – here it is! […]
