Description

Specificity
Anti-SARS-CoV-2 Nucleocapsid, clone NP1-B9, specifically targets an epitope on the SARS-CoV-2 nucleocapsid protein. Futhermore, it is reported to bind to the oligomerization domain of the N protein.
Antigen Distribution
The nucleocapsid protein is expressed in the internal nucleocapsid of SARS-CoV-2.
Background
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), is an enveloped, single-stranded, positive-sense RNA virus belonging to the Coronaviridae family1. The SARS-CoV-2 genome encodes four essential proteins: the spike (S), envelope (E), membrane (M), and nucleocapsid (N) proteins2. SARS-CoV-2 shares 79.6% identity with the original SARS-CoV2. The N protein is 46 kDa and consists of two highly conserved structural domains, the N-terminal domain (NTD) and C-terminal domain (CTD), connected by a linker region. The NTD and CTD are involved in a couple of primary functions, including RNA binding and self-oligomerization3,4. This results in binding to and packaging of the viral RNA genome into a helical ribonucleoprotein5. The N protein is involved in other critical steps of the viral life cycle, including transcription, replication, and modulating infected cell signaling pathways6,7. The N protein is a suitable candidate for vaccine development and diagnostic assays8 for several reasons. It is abundantly expressed during infection and is highly conserved, sharing 90% amino acid homology with the SARS-CoV N protein9. Furthermore, antibodies9,10 and memory T cells11,12 targeting the N protein are identified in the sera of convalescent COVID-19 patients, demonstrating it as immunogenic. The N protein also suppresses antiviral RNAi, evading the innate immune system13, suggesting its potential value as a targeted therapeutic.
