Comparing library preparation methods for SARS-CoV-2 multiplex amplicon sequencing on the Illumina MiSeq platform
Batty, E.M. et al.
bioRxiv 20202020
In the article, Batty, E.M. et al. present their findings from a comparison of three different library preparation methods used in the ARTIC Network protocol for SARS CoV- 2 multiplex amplicon sequencing on the Illumina® MiSeq® platform. The authors report that the ligation-based KAPA HyperPrep method resulted in higher library yield, more total reads, and equal or better overall coverage than the tagmentation-based Nextera Flex or Nextera XT workflows.

Blocking of the CD80/86 axis as a therapeutic approach to prevent progression to more severe forms of COVID-19
Julia et al.
aRxiV.org2020
Julia et al. used KAPA RNA HyperPrep with RiboErase (HMR) Globin to investigate the transcriptional responses of SARS-CoV-2-infected patient samples to the immunomodulating drug Abatacept, and to compare this response to that of cells and blood from Rheumatoid Arthritis patients. The authors used this data to determine whether blocking the CD80/86 axis is a viable therapeutic target to prevent severe immune responses of COVID19 patients.

Hydroxychloroquine inhibits trained immunity – implications for COVID-19
Rother et al.
medRxiV.org2020
Rother, N. et al. constructed total RNA-seq libraries using KAPA RNA HyperPrep Kit with RiboErase (HMR) to perform transcriptome analysis of isolated monocytes of COVID-19 patients. These cells demonstrated increased expression of interferon-stimulated genes, which are likely markers of disease severity as they are associated with a poor clinical outcome. Using the Kapa HyperPrep Kit, the authors also constructed ChIP-seq libraries to investigate the effect of hydroxychloroquine on trained immunity at the functional and epigenetic level.

bioRxiV.org2020
Williamson et al. use the KAPA HyperPlus Library Preparation Kit and KAPA Unique Dual-Indexed Adapters to prepare sequencing libraries from double-stranded cDNAs converted from SARS-CoV-2 viral RNA. Williamson et al. also amplified the resulting libraries using KAPA HiFi HotStart ReadyMix and quantified them with the KAPA Library Quantification Kit prior to paired-end sequencing.

Transcriptional profiling of immune and inflammatory responses in the context of SARS-CoV-2 fungal superinfection in a human airway epithelial model
de Lamballerie, C.N. et al.
bioRxiV.org2020
Following construction of poly(A)-enriched RNA-seq libraries with the KAPA mRNA HyperPrep Kit, de Lamballerie et al. compared the host transcriptional response to SARS-CoV-2 infection alone to that of SARS-CoV-2 with Aspergillus superinfection to elucidate the impact of fungal superinfections on the course and severity of viral infections in respiratory epithelial cells.

The circulating SARS-CoV-2 spike variant N439K maintains fitness while evading antibody-mediated immunity
Thomson, E.C. et al.
bioRxiv 20202020
Immune evasion mutations that maintain virulence and fitness can emerge within the SARS-CoV-2 spike protein, highlighting the need for ongoing molecular surveillance to guide development and usage of vaccines and therapeutics. Thomson, E.C. et al. used the ARTIC network amplicon sequencing protocol and the https://doi.org/10.1101/2020.11.04.355842 to conduct epidemiological and genome surveillance of SARS-CoV-2 and
