Researchers at Calico Life Sciences in a collaboration with the platform manufacturers PacBio (sequencing) and BioNano (optical mapping) produced a fully phased de novo assembly of a human genome. 10X Genomics linked-read technology was also used, and a new method is presented that uses Illumina sequencing of flow cytometry-sorted metaphase chmormosomes.
>20KB High-Pass was used on the BluePippin for the construction of SMRTbell library for PacBio RSII sequencing.

Pacific Biosciences, in conjunction with their research partners, publicly released (in a BioRxiv preprint) the sequences of five complex genomes that were derived using their high-accuracy circular consensus sequencing (the HiFi method, which resequences 15-20kb SMRTbells up to 30X). The genomes include inbred models Mus musculus (house mouse) and Zea mays,(corn) and complex models Fragaria × ananassa (Strawberries) and Rana muscosa (mountain yellow-legged frog). The fifth sequence was a mock metagenomic bacterial community (ATCC MSA-1003).
Three of the libraries use the SageELF for narrow size selections at ~15KB. The BluePippin was used for one genome (beads were used to size select the metagenomic samples.

Little brown bats have experienced a 90% population decline due to fungal pathogen that causes a disease, white-nose syndrome. The authors used ddRADseq to compare surviving and non-surviving individuals. The results indicate shifts in allelic frequencies in genes associated with responses to the disease, suggesting evolutionary adaptation to the syndrome.
Pippin Prep was used to size-select ddRad libraries.

The authors present a restriction enzyme reduced representation sequencing (RE-RRS) method for metagenome profiling of livestock rumen microbial communities. The researchers correlate the profiles with methane production from the animals and compare results to previous 16S sequencing benchmarks.
Pippin Prep was used to size-select amplified sequences.

Collaborators at North Carolina State University report success treating Idiopathic pulmonary fibrosis (IPF) with inhalation treatment with lung spheroid cell-secretome and exosomes using mouse models. IPF is a fatal and incurable form of interstitial lung disease in which persistent injury results in scar tissue formation.
Pippin Prep was used to isolate microRNA sequencing libraries for studying the microRNA profile of exosomes post-treatment.
