Risk stratification of Barrett’s oesophagus using a non-endoscopic sampling method coupled with a biomarker panel: a cohort study

Lancet. 2016, Nov 10; doi: 10.1016/S2468-1253(16)30118-2.
FFPE-extracted DNA was quantified by PCR with primers specific to ALU115 repetitive elements (appendix 1, p 1). At least 10-25 ng quantified DNA was used for library preparation with TP53 Accel-Amplicon comprehensive panel (Swift Biosciences, Ann Arbor, MI, US)…more »

Newborn screening quality assurance program for CFTR mutation detection and gene sequencing to identify Cystic Fibrosis

Journal of Inborn Errors of Metabolism & Screening. 2016, Volume 4:1-11.
All newborn screening laboratories in the United States and many worldwide screen for cystic fibrosis. Most laboratories use a second-tier genotyping assay to identify a panel of mutations in the CF transmembrane regulator (CFTR) gene… more »

Detecting DNA methylation using the Oxford Nanopore Technologies MinION sequencer

bioRxiv. doi:, Epub 2016 Apr 4.
Nanopore sequencing instruments measure the change in electric current caused by DNA transiting through the pore. In experimental and prototype nanopore sequencing devices it has been shown that the electrolytic current signals are sensitive to base modifications, such as 5-methylcytosine…. more »

Single-stranded DNA phages: from early molecular biology tools to recent revolutions in environmental microbiology

FEMS Microbiol Lett. 2016 Mar;363(6). pii: fnw027. doi: 10.1093/femsle/fnw027. Epub 2016 Feb 5.
Single-stranded DNA (ssDNA) phages are profoundly different from tailed phages in many aspects including the nature and size of their genome, virion size and morphology, mutation rate, involvement in horizontal gene transfer, infection dynamics and cell lysis mechanisms. Despite the importance of ssDNA phages as molecular biology tools and model systems, the environmental distribution and ecological roles of these phages have been largely unexplored… more »
