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 […]
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 […]
Nanostring had an interesting poster presented by Joe Beecham at last years AGBT describing their novel single-molecule hybridization-based sequencing chemistry (see AGBT and JPMorgan 2016 coverage from GenomeWeb). This utilizes the Nanostring optical barcodes in a new configuration to deliver Hyb&Seq: no amplification, no enzymes, and no […]
In this post I describe an idea for using SNP fingerprinting for single-cell RNA-Seq to identify which sample each individual cell comes from in a multiplexed library prep. The reason for my thinking about this is that single-cell experiments are expensive. Although the cost-per-cell can […]
We do lots of DNA, RNA and NGS library normalisations mostly by hand after calculating dilutions in Excel. It works well but is cumbersome and prone to error. We’re fortunate to have an Agilent Bravo robot and are now automating more of this with excellent […]
I’m continuing a series of posts that will highlight small advances we’ve made in the lab that are unlikely to be published in their own right, this time its the turn of SPRI-bead clean-ups and how we used them to rescue some samples that would […]
Methylation analysis is hampered by the simple fact that PCR amplification removes methylation marks from native DNA. We came up with a simple idea to produce a thermo-stable DNA methyltransferase to preserve methylation status through PCR cycles, allowing amplification of DNA and simplified analysis. The […]
In a post earlier this week I talked about the hacking of a MiSeq run by MadsAlbertsen, one comment on the post drew my attention to another paper I’d missed where the authors hacked their MiSeq to perform 600bp reads (PE300). Considering this was a […]
I’ll start off by saying not quite, but you can read on to get an idea on how to increase read length of a MiSeq 500cycle v2 kit to get 600bp of data. MadsAlbertsen posted on a SEQanswers thread about their protocol to squeeze a […]
I’m often asked which sample prep method a user should consider for their experiments. In my lab we use a lot of Illumina TruSeq kits; we’ve tried other methods, and do use Rubicon’s Thruplex, but Ilumina’s end-to-end support is useful in a medium sized […]
