Info:
In this Editor’s Choice article from the Molecular Phylogenetics and Evolution journal, researchers provide the first genome-scale analysis of turtle phylogeny using sequence data collected from thousands of ultraconserved elements. Through maximum likelihood, Bayesian, and species tree methods, they produced a single resolved phylogeny. BluePippin was used to prepare the libraries for PCR amplification.

Info:
In this publication in the Journal of Visualized Experiments, scientists at Weill Cornell Medical College and the University of Michigan describe a protocol to map DNA methylation patterns across the genome with next-gen sequencing instead of microarrays. Where input amounts allow, the approach calls for automated DNA size selection using Pippin Prep.

Assessing the utility of whole genome amplified DNA for next-generation molecular ecology

Christopher Blair, C. Ryan Campbell, and Anne D. Yoder
Info:
Scientists at Duke University explored whether whole-genome amplification leads to sequence bias by performing a ddRAD-seq study of grey mouse lemurs using multiple displacement amplification. They conclude that MDA enrichment does not cause systematic bias, opening the doors for studies with low-quantity DNA. The team used Pippin Prep for size selection of the ddRAD-seq library.

PU.1 Opposes IL-7–Dependent Proliferation of Developing B Cells with Involvement of the Direct Target Gene Bruton Tyrosine Kinase

Info:
Scientists from the University of Western Ontario report in this Journal of Immunology paper a research effort to understand how faulty B cell development in mice leads to a form of leukemia. Ultimately, they determined that inducing Btk expression leads to apoptosis, perhaps preventing leukemia formation. Pippin Prep sizing was used for ChIP-seq on an Illumina HiSeq 2000.

Genomic resources for the endangered Hawaiian honeycreepers

Info:
In this BMC Genomics paper, scientists report assembling the genome sequence of Hemignathus virens, a member of the Hawaiian honeycreeper bird family. They identified nearly 4 million SNPs in the genome, as well as some 156,000 SNPs in a RAD tag study of five honeycreeper species that were compared to the reference genome assembly. Paired-end sequencing was perfomed with the MiSeq and HiSeq 2000 after size selection with Pippin Prep.
