Scientific Data

Western Blot Detection of SARS-CoV-2 Nucleocapsid antibody by Western Blot. View Larger

Detection of SARS-CoV-2 Nucleocapsid by Western Blot. Western blot shows recombinant SARS-CoV-2 Nucleocapsid protein. PVDF membrane was probed with 2 µg/mL of Mouse Anti-SARS-CoV-2 Nucleocapsid Monoclonal Antibody (Catalog # MAB10474) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for SARS-CoV-2 Nucleocapsid at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Immunohistochemistry View Larger

SARS-CoV-2 Nucleocapsid in SARS-CoV-2 Infected Human Lung. SARS-CoV-2 Nucleocapsid was detected in immersion fixed paraffin-embedded sections of SARS-CoV-2 infected human lung (left, positive staining) and normal human lung (right, negative control) using Mouse Anti-SARS-CoV-2 Nucleocapsid Monoclonal Antibody (Catalog # MAB10474) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to SARS-CoV-2 infected cells. Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.

Background: Nucleocapsid

SARS-CoV-2, which causes the global pandemic coronavirus disease 2019 (Covid-19), belongs to a family of viruses known as coronaviruses that are commonly comprised of four structural proteins: Spike protein (S), Envelope protein (E), Membrane protein (M), and Nucleocapsid protein (N) (1).  While the S, E and M proteins build up the viral envelop, the N protein is involved transcription, replication and packaging of the viral RNA genome into a helical ribonucleocapsid (RNP) (2, 3).  The SARS-CoV-2 N protein is a ~45 kDa protein composed of two independent structural domains connected by a linker region. The N-terminal region contains an RNA binding domain, the linker region interacts with the M protein and the C-terminal region contains a self-association domain (2,3). The SARS-CoV2 N protein shares 91% and 47% amino acid sequence identity with SARS-CoV-1 and MERS N protein, respectively.  The SARS-CoV-2 N protein displays VSR (viral suppressor of RNA interference) activity in mammalian cells (4). In addition, the N protein is an abundant protein during coronavirus infection and displays high immunogenic activity (5, 6), so it has been used to develop serological diagnostic kit for Covid-19 IgM and IgG antibody tests (7).
