NEBNext® RSV Primer Module is intended for use in cDNA synthesis, amplification, and library preparation upstream of Respiratory Syncytial Virus (RSV) sequencing. The Primer Module can be used upstream of both Illumina® and Oxford Nanopore Technologies® sequencing, when paired with LunaScript Multiplex One-Step RT-PCR Kit and a compatible library prep solution (e.g., NEBNext UltraExpress FS DNA Library Prep Kit or ONT library prep reagents).

  • Full-length coverage of RSV A and RSV B
  • Intentionally designed, balanced, and functionally optimized primer sequences
  • Flexibility to use with Illumina® or Oxford Nanopore Technologies® platforms
  • Timely RSV variant surveillance with NEB’s Primer Monitor tool
  • Primer sequence information can be found in the NEBNext GitHub Repository

Note: This product is intended for research-use only. 

RSV is a virus that commonly infects infants and the elderly, causing severe respiratory symptoms, while leading to milder illness in older children and young adults. For laboratories interested in sequencing the RSV genome, the NEBNext RSV Primer Module contains a curated set of primer mixes for use in RT-PCR upstream of NGS library preparation. Downstream, the libraries are compatible with Illumina or ONT chemistries. Refer to the product manual for the required materials not supplied for your sequencing platform of choice.

The NEBNext RSV Primer Module has undergone extensive QCs to ensure that the primer mixes are balanced, well-aligned with modern strains of RSV, and free of cross contamination. In-house testing includes the full recommended workflow, combining RT-PCR, NGS library prep, and sequencing followed by analysis of sequencing metrics.

Due to its modular nature, and compatibility with a range of downstream sequencing platforms, the NEBNext RSV Primer Module provides flexibility for maximal ease of use. Not only is the NEBNext RSV Primer Module compatible with both Illumina and ONT sequencers, the workflow is automation friendly.  

Full information on the primer sequences included can be found at https://github.com/nebiolabs/rsvab-sequencing. To access up-to-date information on sequence variants that are impacting established primer sets, visit primer-monitor.neb.com.

The NEBNext® RSV primer scheme consists of pan-RSV primers that target both RSV A and RSV B, as well as subtype-specific primers that recognize either RSV A or RSV B. Each primer mix consists of several primer pairs.

Figure 2: Workflow for use of NEBNext® RSV Primer Module for RT-PCR upstream of RSV library prep and sequencing

The NEBNext® RSV Primer Module is designed to be paired with the LunaScript® Multiplex One-Step RT-PCR Kit (NEB #E1555) for streamlined cDNA synthesis and targeted amplification, followed by library construction using either NEBNext UltraExpress® FS DNA Library Prep Kit (NEB #E3340) or Oxford Nanopore Technologies® Native Barcoding Kit.

Figure 3: NEBNext® RSV Primer Module coupled with LunaScript® Multiplex One-Step RT-PCR Kit provides robust RSV amplicon yields


Overlapping amplicons were generated from 100–10,000 total copies of viral gRNA templates, with 1 ng Universal Human Reference RNA (UHR) background, using dual multiplexed RSV-targeting primer pools. The gRNA templates were RSV A gRNA (ATCC® VR1540), RSV B gRNA (ATCC VR-1580), a 1:1 [RSV A : RSV B] gRNA mix, or a 1:1:1:1 [RSV A : RSV B : Influenza A : SARS-CoV-2] mix.
A. 1/10th diluted amplicons were run on TapeStation® using DS 5000 HS reagents without a cleanup. TapeStation traces show expected amplicon peaks within the 400 to 1,400 bp size range.
B. Average amplicon yields (n=3) within 400 to 1400 bp window determined via TapeStation Analysis of diluted post-RT-PCR amplicons.

Overlapping cDNA amplicons were generated from 100–10,000 total copies of viral gRNA templates, with 1 ng Universal Human Reference RNA (UHR) background, using dual multiplexed RSV targeting primer pools. The gRNA templates were RSV A gRNA (ATCC® VR-1540), RSVB gRNA (ATCC VR-1580), a 1:1 [RSV A : RSV B] gRNA mix, or a 1:1:1:1 [RSV A : RSV B : Influenza A : SARS-CoV-2] mix. The NTC template consisted of Nuclease-Free Water. Following targeted amplification, libraries were constructed with the NEBNext UltraExpress® FS DNA Library Prep Kit (NEB #E3340) and sequenced on a NextSeq® 500. 1M read pairs were sampled with seqtk and aligned with Bowtie 2 to a composite RSV A, RSV B, Influenza A, SARS-CoV-2, and human reference genome. Heat map of the average number of reads mapping to amplicons targeting either Pan-RSV, RSV A-specific, or RSV B-specific regions across all RSV and Multi-viral gRNA templates utilized is shown.

Figure 8: NEBNext® RSV Primer Module generates high RSV genome coverage from clinical samples

The NEBNext® RSV Primer Module and LunaScript® Multiplex One-Step RT-PCR Kit (NEB #E1555) were used to generate amplicons from IRBapproved clinical (nasopharyngeal swab) samples. Amplicon sequencing libraries were made for the Oxford Nanopore Technologies® platform (MinION® Flow Cell R10.4.1; high-accuracy basecalling). Each sample initially tested positive for RSV via the BioFire® assay; Ct values shown are from subsequent qRT-PCR assays. The qRT-PCR, targeted whole-genome RT-PCR, library prep, and sequencing of an equal volume library pool of these clinical samples was performed by collaborators at the Applied Physics Laboratory at Johns Hopkins University. Sequencing reads were aligned to a composite reference containing Human (T2T), RSV A (ATCC® VR-1540, and RSV B (ATCC VR-1580) genomes, with MiniMap2. A. Percent of reads that aligned to the human, RSV A, or RSV B reference for each sample; all samples were identified as RSV A. B.
