NEBNext® ARTIC products for SARS-CoV-2 sequencing
Especially with the ongoing emergence of SARS-CoV-2 variants that affect virus transmission and other metrics significant to public health, there is an increasing need for reliable, accurate and fast methods for sequencing SARS-CoV-2. The NEBNext ARTIC kits are based on the original work of the ARTIC Network, who quickly adapted their protocols to SARS-CoV-2 (Josh Quick 2020. nCoV-2019 sequencing protocol v2 (GunIt)).
The ARTIC method is a multiplexed amplicon-based whole-viral-genome sequencing approach (Figure 1), and the NEBNext ARTIC kit options are compatible with Illumina and Oxford Nanopore Technologies sequencing platforms. The two kits compatible with Illumina sequencing generate library inserts of ~150 bp or ~400 bp, for 2 x 75 or 2 x 250 sequencing, respectively (Figure 2). The NEBNext ARTIC SARS-CoV-2 RT-PCR Module contains only the reagents required for cDNA synthesis and targeted cDNA amplification from SARS-CoV-2 genomic RNA.
Express workflow options are provided, with reduced cleanup steps.
Two options for primers are now available, including new VarSkip Short v2 primers, in the NEBNext ARTIC SARS-CoV-2 FS Library Prep Kit (Illumina) (NEB #E7658), NEBNext ARTIC SARS-CoV-2 Companion Kit (Oxford Nanopore Technologies) (NEB #E7660) and NEBNext ARTIC SARS-CoV-2 RT-PCR Module (NEB #E7626).
- The VarSkip (for Variant Skip) Short primers have been designed at NEB to reduce the impact of SARS-CoV-2 variants on amplification and provide improved performance, including with the Omicron variant. The primer pools are balanced for coverage uniformity.
Information on primer overlaps with Omicron and Delta variants.
- The V3 ARTIC primers have been balanced, using methodology developed at NEB based on empirical data from sequencing. In combination with optimized reagents for RT-PCR, the kits deliver improved uniformity of amplicon yields from gRNA across a wide copy number range.
