Anti-SARS-CoV-2 Nucleocapsid Antibody, Human IgG1 is isolated from a SARS-CoV-2 infected patient and is recombinantly produced from CHO cells. 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) .
