This study from Cancer Research UK and a large team of collaborators is a continuation of work evaluating circulating tumor DNA (ctDNA) and the significance of sub-167 base pair cell-free DNA as a marker for tumors. Samples from a cohort of 200 patients were tested and show significantly improved detection of ctDNA by size selecting DNA between 90-150 bp, and using the TAm-Seq technique to detect mutations. PippinHT was used for DNA size selection.

A new protocol from researchers at the Karolinska Institutet and the Ludwig Institute for Cancer Research outline a method for making small RNA sequencing libraries from a single mammalian cell. The method increases sensitivity compared with other methods by using a oligonucleotides to mask ribosomal RNA rather than using a pulldown strategy. Pippin Prep is recommended to isolated miRNA away from other small RNAs.

A large collaboration between international and Brazilian researchers used a suite of epidemiological, spatial, and genomic approaches to characterize Yellow Fever virus transmission in Brazil. The study potentially establishes a framework for monitoring the disease in real time to prevent future epidemics. Pippin Prep used to size select RNA-seq libraries for paired end Illumina sequencing.

Highly sensitive detection of mutations in CHO cell recombinant DNA using multi‐parallel single molecule real‐time DNA sequencing
Joseph Cartwright, Karin Anderson, Joseph Longworth, Philip Lobb, and David James
To improve the quantitative assessment of recombinant DNA in cell lines, University of Sheffield scientists and collaborators developed a PacBio-based method for high-throughput rDNA sequence analysis. The protocol can sequence 40,000 individual recombinant DNA molecules at once to find point mutations. BluePippin was used for purification prior to sequencing.

A Whole Genome Assembly of the Horn Fly, Haematobia irritans, and Prediction of Genes with Roles in Metabolism and Sex Determination
Kranti Konganti, Felix Guerrero, Faye Schilkey, Peter Ngam, et al.
Researchers sequenced, assembled, and annotated the genome of horn fly, a blood-feeding insect that preys on cattle. The 1.14 Gb assembly shows the fly is most closely related to Musca domestica and Drosophila melanogaster. BluePippin was used to size-select mate-pair libraries for genome and transcriptome sequencing using Illumina.
