The domain map of SARS-CoV-2 form the sequence obtained from the first patient in Republic of Korea. The location of each primer set is indicated at corresponding sequence. The primer set from CDC is targeting nucleocapsid protein gene (N) to detect SARS-CoV-2. In-house (IBS) designed primer sets for detecting SARS-CoV-2 target RNA-dependent RNA polymerase gene (RdRP), spike protein gene (S), envelope protein gene (E) and N.
