Coronavirus SARS-CoV-2 Detection and Assay Development
The emergence of new viral diseases, including the coronavirus SARS-CoV-2 (COVID 19), MERS (2015) and SARS (2003) outbreaks, highlights the need for fast methods to detect and identify target viruses at scale. The COVID-19 pandemic also illustrates how research efforts to develop drug treatments or vaccines are accelerated in times of urgent need. The need for supplies and support for scientists working to curtail spread of the SARS-CoV-2 virus is urgent and immediate.
Promega supports scientists working to understand the molecular mechanisms by which emerging viruses infect humans and animals, and to develop accurate detection methods. We provide collaborative technical support, nucleic acid purification expertise, amplification products and labeling technologies that streamline workflows and expedite the work of research labs studying coronaviruses and other emerging viral diseases.
