I’ve been meaning to write up a post on a BioRxiv report from earlier this year: “Scaling single cell transcriptomics through split pool barcoding”1. The Seelig Lab at the University of Washington have developed a single-cell RNA sequencing method to enable labelling RNA molecules with cell-of-origin information using […]
A recent BioRxiv report from the Gerlinger group at ICR describes a targeted ctDNA sequencing method that uses error correcting UMIs to achieve 100% sensitivity for mutant allele frequencies of >0.15%, and 87% at >0.075%, and reduce false-positive mutation calls by 98.6%, without adversely affecting the […]
In this post I wanted to highlight the wonderful “Excel vs R: A Brief Introduction to R” by Jesse Sadler. This is full of useful and practical advice on using R in place of Excel (or any other spreadsheet) for simple data analysis. I use […]
My lab has been a long-time user of Illumina’s transposase exomes for the very simple reason that the 50ng input has been the lowest on the market for number of years*. This made it attractive for cancer samples where we are really limited on DNA availability; […]
Because HPV has such a small and relatively simple genome (8,000 bp encoding 8 genes) it is possible to screen for genetic variation that may underly carcinogenesis. A team from the National Cancer Institute (NCI) has just published the sequencing of over 5,570 human cell and tissue samples – […]
The news about Harvey Weinstein can hardly have escaped the attention of even the most lab-bound post-doc ro PhD student. The investigative journalism at the The New York Times story has led to the downfall of a movie mogul for sexual harassment, unwanted physical contact and other things most of us […]
Hopefully this post is going to pop up as if by magic to all my LinkedIn contacts. This is something I’ve been meaning to do for ages and finally had a go. Thanks to the people at WPBeginner for writing this “how to guide” to make […]
I had the very real pleasure of introducing Prof Lucy Raymond at Biotexcel’s Genomic Medicine 2017 in Cambridge last week. She was speaking in a session that included Dr David Bentley (Illumina Inc – Genomes for Medicine), Prof Stephan Beck (UCL Cancer Institute – Towards Personal Epigenomics), and Prof Sadaf Farooqi (University […]
A short article in todays Times quotes William Cowley parchment makers as saying velum provides the only foolproof way for detecting art forgery. Very simply an artist creates their work on vellum and retains a sample for genetic comparison should a suspected forgery come to […]
The Ecker lab at the Salk Institute published a method for very high-throuphut transcription factor analysis in Nature Protocols yesterday: Mapping genome-wide transcription-factor binding sites using DAP-seq. The method is elegantly simple in its concept; PCR-free libraries from native gDNA are hybridised with affinity-tagged in vitro-expressed transcription factors, […]
