Vijaykumar Chennupati, Diogo Veiga, Kendle Maslowski, Nicola Andina, et al.
Info:
Scientists studying the ribonuclease inhibitor protein found that it controls translation of GATA1 and thereby regulates erythropoiesis, helping to explain anemia-associated diseases caused by mutations in ribosomal proteins. For this work, the team size-selected libraries for an RNA-seq workflow using a PippinHT instrument.

Info:
Scientists from Baylor University Medical Center studied the chemoprotective role of oligomeric proanthocyanidins, finding that they inhibited cellular proliferation and spurred apoptosis. RNA sequencing data showed that these elements disrupted self-renewal pathways. The team used PippinHT to size-select pooled libraries prior to RNA sequencing.

Info:
In this paper, scientists from the University of Bern and collaborators report the identification and purification of a protease that’s an important neurotoxin element in spider venom. PippinHT was used to size-select cDNAs prior to sequencing.

Transcription-associated mutation promotes RNA complexity in highly expressed genes — a major new source of selectable variation
February 2018
Authors:
Shengkai Pan, Michael Bruford, Yusong Wang, Zhenzhen Lin, et al.
Info:
In this project, researchers studied transcriptomes in falcons, mice, and chickens and found that highly expressed genes are more likely to alternatively spliced. They also studied methylation patterns and its effect on alternative splicing. For this work, the team used SageELF to size and separate fractions for Iso-Seq analysis on the PacBio RS II system.

Assembly and RNA‐free annotation of highly heterozygous genomes: The case of the thick‐billed murre (Uria lomvia)
January 2018
Authors:
Anna Tigano, Timothy Sackton, and Vicki Friesen
Info:
Researchers at Queen’s University and Harvard teamed up for an effort to assemble the highly heterozygous genome of an arctic colonial seabird. The found that the platanus assembler outperformed other methods, producing an assembly with an impressive 15.8 Mb N50. DNA integrity was evaluated using the Pippin Pulse.
