Def Leppard are playing “Pour some sugar on me” while we wait for Nick Loman to walk on stage – not sure if this was intentional.
Nik wanted to set the record straight on the size on the MinION: it is not the length of an iPhone (Loman et al. Bioinformatics 2014), or an office stapler (Watson et al bioRxiv 2015), and recently reviewers asked Nik to remove a reference to a chocolate bar. It is only a decade since Solexa sequenced PhiX…and now we’ve got “10X on X Ten”. Shawn’s lab got the GemCode platform in May/June and have been working with it ever since. The V1 10X chemistry did not work on the X Ten platform, and Shawn was reluctant to answer a questions from Mike Quail (WTSI) about how to do this. GemCode requires both a standard TruSeq genome and a 10X genome to be run. The Chromium chemistry gets rid of the need for the TruSeq library. Shawn recommended aiming for 120Gb of sequence, 425 million reads, to get the best from the protocol. This is working well in their hands and variant calling concordance from a single nanogram library compared to a standard 1ug input is 0.999, only 0.7% of the genome is missing due to lack of coverage, showing that the 1ng libraries are very diverse. All in all a pretty good experience so far at Hudson Alpha.
Shawn spent some time talking about what they saw that was new information compared to what could be seen with a standard library prep. He showed a lovely example of many mis-sense mutations phased in a healthy individual confirming only one allele was faulty. Also showed 10X sequencing of non-Human genomes – the clouded leopard genome.
That’s almost it…there are three more talks but I’m going to Tweet those instead. See you at the party.




You always focus on the point of great interest. Well done.
very good idea. thanks 🙂
