A novel coronavirus (SARS-CoV-2) has been shown to be highly contagious and to cause many severe respiratory diseases in humans. The virus is a type of coronaviruses that has a single-stranded RNA genome, which is responsible for encoding several key proteins. With the outbreak of SARS-CoV-2 in Wuhan, Hubei Province, China, a number of in-vitro diagnostics (IVD) kits have been developed by using various PCR-based technologies, such as rRT-PCR, for screening the virus emergence in different populations. rRT-PCR has been considered as a benchmark for detecting and quantifying RNA targets and is being broadly used in clinical diagnosis. In rRT-PCR assays, an oligonucleotide probe will be designed to bind with the key sequence of SARS-CoV-2. Meanwhile, the probe will cleave when the Taq polymerase is added into this detection system. The cleavage will be detected once the fluorescent signal being released. Learn more: rRT-PCR Detect SARS-CoV-2 service
