@Illumina #NovaSeq new mini flowcell

By | June 21st, 2018|Categories: Core facilities, Next-generation sequencing|0 Comments

Illumina released a new NovaSeq flowcell today: S Prime (SP). This allows users to run a very small number of samples and is much more akin to a HiSeq flowcell; one SP flowcells generates 1.6 billion reads or about 4-5 lanes of a HiSeq. It […]

Illumina index sequencing – where is my sample?

By | January 16th, 2018|Categories: Core facilities, Next-generation sequencing|0 Comments

Indexed sequencing is vital to the delivering cost-effective, and statistically robust, experiments. Nearly all non-WGS projects are indexed to some degree so understanding how the indexing works is useful; fortunately Illumina produced this handy guide for users: Indexed sequencing overview. After indexed sequencing our reads […]

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! […]

Illumina released a white paper this week describing their efforts to understand the index-swapping issues with the ExAmp chemistry. This story has been covered many times and got lots of Tweets in the days since the BioRxiv paper from Stanford was uploaded. Megan Molteni at Wired wrote a lengthy […]

What does RNA-Seq mean to you

By | March 28th, 2017|Categories: Core facilities, Methods and applications, Next-generation sequencing|1 Comment

This post is a follow on from my ABRF2017 presentation this morning. Slides are available on SlideShare. RNA-Seq is the most widely published NGS method, but what do researchers mean by the term “RNA-Seq”? Virtually none of them mean sequencing of RNA. Most are talking […]

MinION or GridION for your core lab

By | March 17th, 2017|Categories: Core facilities, Nanopore sequencing|2 Comments

Clive Brown presented a webinar on Tuesday with multiple updates on Oxford Nanopore technology, Keith Robison covered them all over at OmicsOmics, but I’ll just be focussing on the launch of GridION X5. If you want to know more about GridION, PromethION, Throughput, 1D^2 Chemistry, Basecalling, the FPGA Basecalling Accelerator, and a […]

NeoPrep is dead….what does this mean for Illumina

By | February 22nd, 2017|Categories: Core facilities, Nanopore sequencing, Next-generation sequencing|Tags: |0 Comments

Illumina have finally dropped the NeoPrep from their lineup after a short but pretty rocky road. Launched at AGBT15 the instrument promised hassle free library prep automation for users that did not require full 96well plate production-scale solutions. Early access users I spoke to at […]

(almost) everything you wanted to know about @illumina NovaSeq…and some stuff you didn’t

By | January 26th, 2017|Categories: Core facilities, Next-generation sequencing|4 Comments

Introducing NovaSeq This is the first part of a 2 part blog. Part 1 “everything you wanted to know about NovaSeq” covers the technical aspects of NovaSeq, Illumina’s latest sequencer launched on Jan 9th 2017. The instrument is very clearly the next proper step in Illumina technology, which […]
