Epidemiological Research Solutions for SARS-CoV-2 (COVID-19)
Epidemiological surveillance is conducted to ensure viral diseases match the reference strain and to monitor possible mutations, since any changes in the viral genome can impact public health policies and options, how the illness spreads in the population, potential study of treatment options, and vaccine development research. Thermo Fisher Scientific has a complete solution to assist scientists who are conducting epidemiological studies.
Virus typing
Identifying the types and subtypes of viruses is essential to good disease control. A wide variety of research methods can be used to differentiate virus variants of which molecular techniques are used most frequently. By sequencing a specific variable region of the viral genome, one can investigate whether selected isolates of a certain species are phylogenetically related. A major challenge for microbiologists and virologists is the prediction of patterns of evolution and emergence of disease agents. RNA viruses like SARS-CoV-2 (the coronavirus responsible for COVID-19) share the biological feature of high genetic variability, which causes them to appear as clouds of mutants. Advanced molecular technologies like next-generation sequencing (NGS) enables complete SARS-CoV-2 genome sequencing, including all variants and potential serotypes.

Select products for targeted sequencing workflow
Several methods have been developed for the targeted enrichment of genomic DNA for a variety of clinical and research applications. Typically, they are based on a multiplexed PCR amplification reaction and DNA hybridization. All these DNA enrichment methods rely heavily on fragmentation of genomic DNA prior to amplification, resulting in relatively short (less than 1000 base-pair) sequencing templates.
Targeted sequencing workflow implementing target captured by hybridization includes several general steps - sample preparation, library construction, target enrichment, sequencing and analysis.
- Circulating tumor DNA profiling by next generation sequencing reveals heterogeneity of crizotinib resistance mechanisms in a gastric cancer patient with MET amplification.
- Clinicopathologic characteristics and survival outcome in patients with advanced lung adenocarcinoma and KRAS mutation.
- The characteristics of ctDNA reveal the high complexity in matching the corresponding tumor tissues.
- Capture-based next-generation sequencing reveals multiple actionable mutations in cancer patients failed in traditional testing.
- Application of targeted enrichment to next-generation sequencing of retroviruses integrated into the host human genome.
- Fine-scale chromatin interaction maps reveal the cis-regulatory landscape of human lincRNA genes.
De novo sequencing using Ion Torrent NGS
In addition to targeted sequencing, which covers >99% of the viral genome and variants, Ion Torrent systems can be used for hypothesis-free (de novo) genome sequencing of SARS-CoV-2 by NGS.

Variant confirmation with Sanger sequencing
While NGS analyses can be used for complete viral genome sequencing and variant detection of the SARS-CoV-2 genome, Sanger sequencing is still considered the gold standard sequencing method for verifying the sequence of specific genes, including those already sequenced through Illumina NGS due to its high degree of accuracy. It is being used to sequence and confirm variants of different SARS-CoV-2 genes within clusters of symptomatic and asymptomatic individuals (1-4).
The entire workflow can be completed, from sample to answer, in less than one workday. We offer products to support the entire workflow from PCR amplification to data analysis. The SeqStudio genetic analyzer is an affordable, low-throughput cartridge-based benchtop genetic analyzer that eliminates complex instrument set-up to deliver Sanger sequencing runs in as little as 30 minutes.

Virus monitoring
Accurate understanding and monitoring of the SARS-CoV-2 virus is essential for effective response. Monitoring is important to help public health decision makers know where the disease is, how quickly it is spreading, and to longitudinally monitor the effectiveness of public health measures on outbreak containment or mitigation. Monitoring also plays a role in understanding cross-species transmission of the virus and its spatial spread over evolutionary time and at human-wildlife interfaces. We offer several cost-effective molecular tools for SARS-CoV-2 disease monitoring research, from technologies like real-time PCR and Sanger sequencing for specific genes/targets to whole genome sequencing to capture all variants using NGS.

SARS-CoV-2 monitoring with Sanger sequencing and fragment analysis by capillary electrophoresis
Sanger sequencing is a simple, fast, and cost-effective orthogonal gold-standard method to monitor SARS-CoV-2 identified by NGS or by RT-PCR. The entire workflow can be completed, from sample to answer, in less than one workday. It is being used by several labs globally to confirm the identity of SARS-CoV-2 in wastewater samples. It is also being used to confirm the origin and cross-species transmission of different coronaviruses, which is important in understanding potential sources of zoonotic transmission (1-3).
Fragment analysis by capillary electrophoresis (CE) provides an attractive method for rapid testing of multiple targets. Multiplexed qPCR solutions detect small numbers of pathogens. The relatively small capacity of multiplexed qPCR reactions can limit throughput when large numbers of targets or pathogens need to be detected. Fragment analysis gives researchers another tool for analyzing the presence of genomic sequences of pathogenic organisms using a method that is rapid, simple, and sensitive.
- Protocol: Detection of RNA from SARS-CoV-2 using fragment analysis ›
- Application Note: Multiplex target fragment analysis for detection of viral pathogens including SARS-CoV-2 ›
Fragment analysis by CE can be used to identify microbial signatures associated with different disease phenotypes. It relies on amplification of 16S-23S rRNA interspace (IS) regions in bacteria to produce PCR fragments that vary in length and frequency depending upon bacterial species. Each PCR fragment can be separated and detected on a genetic analyzer. The resulting fragment patterns are compared to a curated database to determine the species present in the sample.
