COVID-19, the 2019 disease outbreak, continues to cause severe mortality worldwide. Fast and reliable tests that identify the SARS-CoV-2 virus, which is responsible for causing the COVID-19 disease, are crucial for controlling the spread of the virus. Antigen tests are ideal for the rapid diagnosis of COVID-19. Current antigen tests for COVID-19 detect the SARS-CoV-2 nucleocapsid (N) protein. The nucleocapsid is the most abundant protein produced by the virus upon infection, which makes it a superior target for detection by an antigen test. Nucleocapsid proteins from several coronaviruses, including SARS, have previously been shown to be modified by posttranslational modification …
