Rapid SARS-CoV-2 Detection in Wastewater

Promega Corporation has developed a complete workflow that enables wastewater testing laboratories, including public health organisations, to rapidly assess the health of entire communities from a single sample. The Maxwell® RSC Enviro Total Nucleic Acid Kit and Wizard® Enviro Total Nucleic Acid Kit join a growing portfolio of products that support wastewater surveillance to monitor the spread of SARS-CoV-2.

Promega scientists recently published a study detailing direct capture methods for rapid and high-yield purification of viral nucleic acids from wastewater. These methods overcome the shortcomings of traditional precipitation-based isolation of viral particles, which fail to capture the degraded viruses present in wastewater. The publication demonstrates that direct capture methods produce samples that are compatible with RT-qPCR for monitoring infection levels and next-generation sequencing (NGS) for detecting viral variants.

The methods form the basis of the new Maxwell® RSC Enviro Total Nucleic Acid Kit, an automated method for purification of viral nucleic acids, as well as the manual Wizard® Enviro Total Nucleic Acid Kit. Both kits are designed to work with the large sample volumes required for wastewater testing and remove inhibitors that can disrupt downstream testing. The protocols can also be altered to process solids extracted from wastewater, in addition to only liquids.

The purification kits can be used with the SARS-CoV-2 RT-qPCR Kit for Wastewater to form a complete workflow for monitoring SARS-CoV-2 levels in wastewater. The workflow moves from sample to results in less than four hours, offering quick answers to inform decisions.
