The SARS-CoV-2 (2019-nCoV) Nucleocapsid (N) is a structural protein that plays an important role in viral life cycle including replication, transcription, and genome packaging. N-protein, being one of the predominantly expressed proteins at the early stage of SARS-CoV infection, and detection efficiency of the N-protein is significantly higher than SARS-CoV specific IgG, SARS-CoV RNA markers, simultaneously, so N-protein has been an attractive tool for early diagnosis. N-protein has also been tested as a protective vaccine against SARS-CoV infection. So SARS-COV-2(2019-nCoV) N Protein can be used not for diagnosis, it could also be a potential vaccine candidate to against 2019-nCov/COVID.
