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! […]

Update on @illumina index-swapping

By | April 21st, 2017|Categories: "Experimental design controls etc", Core facilities, Design, Methods and applications, Next-generation sequencing|0 Comments

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 […]

Mass-cytometry webinars from @Fluidigm

By | March 31st, 2017|Categories: Methods and applications, Other stuff|0 Comments

The Helios/CyToF mass-cytometry technology is making waves here in our Flow Core and is likely to be a useful addition to multi-omic studies. Fluidigm have a series of webinars that I thought readers of Core-Genomics might be interested in: Decoding human tumors and healthy tissue […]

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 […]

HMW DNA extraction for long-reads on @nanopore or @10XGenomics

By | March 28th, 2017|Categories: 10X Genomics, Methods and applications, Next-generation sequencing|8 Comments

Long-reads require long DNA molecules which require high molecular weight (and undamaged) DNA. Extraction with your standard column is unlikely to be optimal. I’m starting to look at the best methods for HMW DNA extraction for long-read applications as my lab is supporting a couple of […]

10X Genomics 10x cheaper…and better too!

By | March 22nd, 2017|Categories: "Experimental design controls etc", 10X Genomics, Methods and applications, Next-generation sequencing, Single-cell sequencing, Uncategorized|0 Comments

Confession: this post may not actually make your 10X Genomics experiments ten times cheaper…but implement Demuxlet in your workflow and with the right sort of experiment you might just get there! Single-cell RNA-Seq might just have got a whole lot cheaper, thanks to a method […]

Cas9 CATCH-seq and lego-brick microfludics

By | March 15th, 2017|Categories: Methods and applications, Nanopore sequencing, Next-generation sequencing, Other stuff|Tags: , , |0 Comments

Two publications presenting really cool technologies recently caught my attention: “Lego for molecular biology” and “CATCH-Seq: CRISPR for target enrichment sequencing”. Both are technologies I’d like to play with, and my son can join in the Lego modelling if we build some here in Cambridge! Lego […]

A paper published one month ago in Nature Genetics: Stessman et al 2017, by Evan Eichler’s group at HHMI, reported finding 91 genes associated with neuro-developmental disorders. 25 of these were enriched in autism probands and the authors reported a “network associated with high-functioning autism (full-scale IQ >100)”.

APOBEC-Seq for DNA methylation without the bisuflite

By | March 2nd, 2017|Categories: Methods and applications, Next-generation sequencing|Tags: , |1 Comment

For me one of the top talks at #AGBT17 was in a concurrent session. Theodore Davis from New England Biolabs presented “APOBEC-Seq: An enzymatic method for methylome analysis at single-base resolution without bisulfite treatment.” His talk focused on some of the cons of using sodium bisulfite sequencing for methylation in epigenetic […]

Hydroxymethylation (hmC) papers from CEGX

By | February 22nd, 2017|Categories: Methods and applications, Next-generation sequencing|Tags: , , |0 Comments

Cambridge Epigenetix (@CEGX_news) have a list of almost 50 papers on their website using their technology for DNA methylation and hydroxymethylation analysis, which I thought readers of CoreGenomics might be interested in. They also have a list of Epigenetics Conferences coming up….enjoy! The papers: Chen et […]
