Anti-SARS-CoV-2 Nucleocapsid Antibody, Human IgG1 (AS41)

Anti-SARS-CoV-2 Nucleocapsid Antibody, Human IgG1 (AS41) (NUN-S41) is isolated from a SARS-CoV-2 infected patient and is recombinantly produced from human 293 cells (HEK293) . As verified by binding test with N-NTD (Cat. No. NUN-C5143) and N-CTD (Cat. No. NUN-C5145) protein, this antibody can only bind to N-CTD (AA Ser 255 - Pro 364) . ELISA test validated that this antibody can bind multiple N protein variants (Cat. No. NUN-C52H8) with similar affinity as compared to the wild type N protein (Cat. No. NUN-C5227) .

Background

Nucleocapsid (N) protein is the most abundant protein found in coronavirus. CoV N protein is a highly immunogenic phosphoprotein important for viral genome replication and modulation of cell signaling pathways. It was first identified by a research team while they were screening for ADP-ribosylated proteins during coronavirus (CoV) infection (Grunewald M. E., et al. 2017, Virology; 517: 62-68) . The array of diverse functional activities accommodated in N protein makes it more than a structural protein but also an interesting target in the development of antiviral therapeutics. Because of the conservation of N protein sequence and its strong immunogenicity, N protein of coronavirus is chosen as a diagnostic tool.
