Pinpointing sources of unlinked SARS-CoV-2 cases supports rapid public health response. Using high-quality genetic fingerprinting, DeepMARK™ can enable rapid community case tracing by identifying transmission paths, clusters, and viral contagiousness. DeepMARK™’s increased sensitivity also allows for asymptomatic and recovering cases to be more thoroughly evaluated for contagiousness.
For researchers studying contagiousness, SARS-CoV-2 sgRNA is a recognized marker of active viral replication linked with contagiousness2 and offers several advantages. While viral culture is the gold standard, it is slow, expensive, and requires a biosafety level 3 (BSL3) laboratory, requirements prohibitive for the vast majority of samples. Using DeepMARK™, clinical samples can be safely and efficiently profiled using a simple workflow.
SgRNA as a marker of viral replication is also a well-recognized efficacy measurement in SARS-CoV-2 vaccine development3. Thus, comprehensive sgRNA profiling by DeepMARK™ could facilitate more efficient vaccine discovery.
“Genetic fingerprinting enables quicker and deeper analysis of viral spread. This tool has enhanced our capacity to understand SARS-CoV-2 precisely and contributes to the ongoing fight against COVID-19.” said A/Prof Hsu Li Yang, Vice Dean, Global Health, Saw Swee Hock School of Public Health, National University of Singapore.
