SARS-CoV-2 McGill Nextera Flex sequencing protocol_SS_V3_LA1_5uLRT Resource Report Resource Website |
Sarah Reiling, Marie-Michelle Simon, Anne-Marie Roy, Shu-Huang Chen, Josh Quick, Ioannis Ragoussis | DOI:10.17504/protocols.io.bisbkean | Coronavirus Method Development Community, McGill Genome Centre | How the Nextera DNA Flex Assay Works The Nextera DNA Flex library prep kit uses a bead-based transposome complex to tagment genomic DNA, which is a process that fragments DNA and then tags the DNA with adapter sequences in one step. After it is saturated with input DNA, the bead-based transposome complex fragments a set number of DNA molecules. This fragmentation provides flexibility to use a wide DNA input range to generate normalized libraries of consistent tight fragment size distribution. Following tagmentation, a limited-cycle PCR adds Nextera DNA Flex-specific index adapter sequences to the ends of a DNA fragment. This step enables capability across all Illumina sequencing platforms. A subsequent Sample Purification Beads (SPB) cleanup step then purifies libraries for use on an Illumina sequencer. The double-stranded DNA library is denatured before hybridization of the biotin probe oligonucleotide pool. PCR Amplicons for Nextera FlexWhen starting with PCR amplicons, the PCR amplicon must be > 150 bp. The standard clean up protocol depletes libraries Therefore, Illumina recommends that amplicons Shorter amplicons can otherwise be lost during the library cleanup step. Tagmentation cannot add an adapter directly to the distal end of a fragment, so a drop in sequencing coverage of ~50 bp from each distal end is expected. To ensure sufficient coverage of the amplicon target region, design primers to extend beyond the target region by 50 bp per end.

INSIGHT: a scalable isothermal NASBA-based platform for COVID-19 diagnosis Resource Report Resource Website |
Qianxin Wu, Chenqu Suo, Tom Brown, Tengyao Wang, Sarah Teichmann, Andrew Bassett | DOI:10.17504/protocols.io.bghsjt6e | Coronavirus Method Development Community | We present here INSIGHT (Isothermal NASBA-Sequencing based hIGH-througput Test): a two-stage COVID-19 testing strategy, using a combination of an isothermal NASBA reaction and next generation sequencing. From commercially acquired human saliva with spiked-in viral RNA as input, the first stage employs isothermal amplification of viral RNA to give a rapid result in one to two hours, using either fluorescence detection or a dipstick readout, whilst simultaneously incorporating sample-specific barcodes into the amplification product. In the first stage, fluorescent viral RNA detection can be consistently achieved at 10-100 copies per 20 μl reaction. The second stage pools post-amplification barcoded products from multiple samples for scalable sequencing that could be centralised, to further improve the accuracy of the test in a massively parallel way. Our two-stage testing strategy is suitable for further development into a home-based or point-of-care assay, and is potentially scalable to population level. | Wellcome Sanger Institute, Wellcome Genome Campus, Hinxton, Cambridge CB10 1SA, UK, Wellcome Sanger Institute, Wellcome Genome Campus, Hinxton, Cambridge CB10 1SA, UK; Department of Paediatrics, Cambridge University Hospitals, Hills Road, Cambridge CB2 0QQ, UK, Department of Chemistry, University of Oxford, Chemistry Research Laboratory, 12 Mansfield Road, Oxford OX1 3TA UK, Department of Statistical Science, University College London, 1-19 Torrington Place, London WC1E 7HB, UK, Wellcome Sanger Institute, Wellcome Genome Campus, Hinxton, Cambridge CB10 1SA, UK; Department of Physics/Cavendish Laboratory, University of Cambridge, JJ Thomson Ave., Cambridge CB3 0HE, UK, Wellcome Sanger Institute, Wellcome Genome Campus, Hinxton, Cambridge CB10 1SA, UK | 1 | 2020 | Qianxin Wu, Chenqu Suo, Tom Brown, Tengyao Wang, Sarah Teichmann, Andrew Bassett 2020.

SARS Direct Saliva Protocol Takarabio Resource Report Resource Website |
Timothy Hamerly, Caroline J Stephenson, Borja Lopez-Gutierrez, Rhoel Dinglasan | DOI:10.17504/protocols.io.btzsnp6e | Coronavirus Method Development Community, Dinglasan Laboratory | Diagnostic testing for SARS-CoV-2 by RT-qPCR has steadily increased since the COVID-19 pandemic began, resulting in the development of protocols for testing from a variety of biological matrices. Initial testing focused on nasopharyngeal and oropharyngeal swabs, which are invasive and require trained health care professionals to perform the sample collection, resulting in a bottleneck in testing. Saliva has emerged as a viable sample specimen for virus detection and can be self-collected with little instruction. Further, it has been demonstrated that virus detection is possible without the need for complex extraction protocols, including commercially available kits. However, a potential pitfall of available kits is the lack of comprehensive testing during development using contrived biological samples containing intact, heat inactivated SARS-CoV-2 virus in the appropriate matrix (e.g., saliva). We have found the Takara Direct One-Step RT-qPCR Mix for SARS-CoV-2 kit to be a cost-effective alternative for testing the direct detection of virus in saliva when compared with magnetic bead-assisted extraction systems, with minimal modifications from the manufacturers protocol. We have found that successful detection of virus requires the addition of a proteinase K digestion step, an increase of the reverse transcriptase time, and 3-step cycle (compared with a 2-step cycle in the manufacturers documentation). These changes allow for the successful detection of SARS-CoV-2 virus with a minimal increase in Ct values for RNase P and viral N-gene transcripts when compared with magnetic bead-assisted extractions kits. Implementing these critical steps will help end-users avoid false negatives. | University of Florida, University of Florida Emerging Pathogens Institute, University of Florida Emerging Pathogens Institute, University of Florida Emerging Pathogens Institute | 2 | 2021 | Timothy Hamerly, Caroline J Stephenson, Borja Lopez-Gutierrez, Rhoel Dinglasan 2021.

A protocol for massively parallel diagnosis and genome sequencing of SARS-CoV-2 Resource Report Resource Website |
Leigh Monahan, Kay Anantanawat, Joyce To, Aaron Darling | DOI:10.17504/protocols.io.betrjem6 | Coronavirus Method Development Community | Managing the current COVID-19 pandemic requires diagnostic testing at an unprecedented scale. However, the crisis has revealed severe deficiencies in our capacity to perform such testing. Here we build on the work of others (1-3) to develop a protocol that not only enables many thousand diagnostic tests to be run in parallel, but also provides near-whole genome sequencing data to facilitate phylogenetic analysis and contact tracing. One of the key features of our protocol is a magnetic bead-based strategy for RNA capture that may circumvent the need for SARS-CoV-2 RNA extraction, currently one of the major bottlenecks in both reagent supply and hands-on sample processing time. This approach also eliminates the requirement for per-sample reverse transcription, significantly reducing per-sample costs. The major steps in our wet lab workflow can be summarised as follows. First, we generate a collection of bead-bound, single-stranded DNA probes tiling the entire SARS-CoV-2 genome. Multiple uniquely barcoded probe sets are prepared, each of which are used to capture viral RNA directly from patient swab samples via DNA/RNA hybridisation. Samples are combined together at this stage, enabling cDNA synthesis to be performed in a single pooled reaction. Finally, multiplex PCR is used to generate a library of overlapping amplicons ready for Illumina sequencing. A schematic overview of the workflow is attached below, along with a more detailed figure depicting the various stages of library preparation.Referenceshttps://docs.google.com/document/d/1kP2w_uTMSep2UxTCOnUhh1TMCjWvHEY0sUUpkJHPYV4/previewhttps://www.protocols.io/view/ncov-2019-sequencing-protocol-bbmuik6w/abstracthttps://www.biorxiv.org/content/10.1101/2020.03.20.001008v1.full.pdf | University of Technology Sydney, University of Technology Sydney, University of Technology Sydney, University of Technology Sydney | 1 | 2020 | Leigh Monahan, Kay Anantanawat, Joyce To, Aaron Darling 2020.

A lateral flow-based at-home test for detection of SARS-CoV-2 Resource Report Resource Website |
Peng Xu, Venice Servellita, Krzysztof Langer, Dan Weisgerber, Gordon Murtaugh, Adam R Abate, Charles Chiu | DOI:10.17504/protocols.io.bs8bnhsn | Coronavirus Method Development Community, UCSF | We have developed a highly sensitive and specific LAMP(loop-mediated amplification)-based assay for thedetection of SARS-CoV-2 that can potentially be used for at-home and point-of-care (POC) testing. The assayincludes only three simple steps: (1) heat inactivate the sample mixed with lysis buffer and add LAMP reagentmix, (2) incubate the reaction on a heating device, and (3) read the result by inserting a lateral flow strip intothe tube. Performance is comparable to gold-standard RT-PCR testing, as the assay is based on nucleic aciddetection rather than antigen detection which is used by the majority of lateral flow strip-based assays. There isminimal pre-processing involved and no bulky instrumentation needed, and non-lab professionals can followthe instructions and understand the results easily. The assay targets the SARS-CoV-2 nucleoprotein (N) geneand is capable of detecting as low as 4.0 copies per reaction (0.5 copies/μL) of SARS-CoV-2 RNA,demonstrating no cross-reactivity with a panel of 20 other respiratory pathogens. Furthermore, the test can berun on multiple sample types, including nasopharyngeal and/or oropharyngeal swab and saliva samples.Overall, this assay provides a rapid (sample-to-answer turnaround time of ~40 min), accurate, and affordablesolution to the challenge of at-home diagnostics for SARS-CoV-2. | Department of Bioengineering and Therapeutic Sciences, California Institute for Quantitative Biosciences, University of California, San Francisco, California, USA, Department of Medicine, Division of Infectious Diseases, University of California San Francisco, San Francisco, CA, USA, Department of Bioengineering and Therapeutic Sciences, California Institute for Quantitative Biosciences, University of California, San Francisco, California, USA, Department of Bioengineering and Therapeutic Sciences, California Institute for Quantitative Biosciences, University of California, San Francisco, California, USA, Department of Bioengineering and Therapeutic Sciences, California Institute for Quantitative Biosciences, University of California, San Francisco, California, USA, Department of Bioengineering and Therapeutic Sciences, California Institute for Quantitative Biosciences, University of California, San Francisco, California, USA, Department of Medicine, Division of Infectious Diseases, University of California San Francisco, San Francisco, CA, USA | 1 | 2021 | Peng Xu, Venice Servellita, Krzysztof Langer, Dan Weisgerber, Gordon Murtaugh, Adam R Abate, Charles Chiu 2021.
