Anti-SARS-CoV-2 Nucleocapsid Antibody, Human IgG1 (AS95) is isolated from a SARS-CoV-2 infected patient and is recombinantly produced from human 293 cells (HEK293). This monoclonal antibody is purified by Protein A affinity chromatography. 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-NTD (AA Gly 44 - Glu 174). ELISA test validated that this antibody can bind multiple N protein variants with similar affinity as compared to the wild type N protein (Cat.No. NUN-C5227).
This product can recognize SARS-CoV-2 Nucleocapsid protein. Cross-reactivity with Nucleocapsid protein of other coronaviruses has not been tested.
This antibody can be paired with other Anti-SARS-CoV-2 nucleocapsid antibodies to detect SARS-CoV-2 nucleocapsid protein in sandwich ELISA or LFA assay.

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.
