One of the primary advantages next-generation sequencing (NGS) provides over other methods of analysis is that it is an effective and high-throughput solution for screening multiple samples and detecting viruses without prior knowledge of an infectious agent. Among its core capabilities, NGS workflows can be used to detect SARS-CoV-2 virus, perform surveillance and epidemiological studies, track mutational changes in the virus, enable unbiased pathogen discovery, and analyze potential susceptibility and human response to SARS-CoV-2 infection.

Identifying SARS-CoV-2 Variants

Multiple SARS-CoV-2 variants are circulating globally, some of which are reported to spread more easily and faster than others. Now you can sequence 6,000 SARS-CoV-2 libraries in a single flow cell using the high-throughput NEXTFLEX® Variant-Seq™ SARS-CoV-2 workflow optimized to quickly, easily, and affordably identify all mutations, including the Delta Variant of Conceren (VOC), in a PCR-positive sample.

Automation supports a lab’s ability to rapidly and safely perform NGS analysis of SARS-CoV-2 samples. Our workflow automates nucleic acid isolation right through to library-prep analysis, simplifying library preparation, mitigating risk of lab-acquired infections, increasing throughput, and reducing variability.

Streamlined WGA Workflow Simplifies Variant Identification While Increasing Throughput

It’s important to know which variant is in a positive COVID-19 sample. After identifying a positive COVID-19 sample, the NEXTFLEX® Variant-Seq™ SARS-CoV-2 kit v2 simplifies the identification of SARS-CoV-2 mutations. With the incorporation of normalization beads, the NEXTFLEX® Variant-Seq™ SARS-CoV-2 v2 kit reduces turn-around time by up to three hours mostly due to eliminating the need for individual library quantification prior to the pooling step.

Automate Your Variant Detection

Pre-programmed protocols are available automating the NEXTFLEX® Variant-Seq SARS-CoV-2 kit on the Sciclone® G3 NGSx, Sciclone® G3 NGSx iQ and JANUS® G3 liquid handlers. These multiple automation options offer labs the flexibility to meet their specific throughput and hands-on time needs.

Library QC

The LabChip® GX Touch nucleic acid analyzer using the NGS 3K assay delivers automated analysis of the sizes and profiles of NGS libraries for required quality assessment prior to sequencing. With flexible throughput options and multiple data visualization choices, the LabChip® GX Touch nucleic acid analyzer simplifies library QC.
