Anti-SARS-CoV-2 Nucleocapsid Antibody, Human IgG1 (AS95) (MALS verified)

  • Source
    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).
  • Isotype
    Human IgG1/kappa
  • Specificity
    This product can recognize SARS-CoV-2 Nucleocapsid protein. Cross-reactivity with Nucleocapsid protein of other coronaviruses has not been tested.
  • Application
    This antibody can be paired with other Anti-SARS-CoV-2 nucleocapsid antibodies (Cat. No. NUN-CH15) to detect SARS-CoV-2 nucleocapsid protein in sandwich ELISA or LFA assay.
  • Purity

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Formulation

    Supplied as 0.2 μm filtered solution in PBS, pH7.4 .

Immobilized Anti-SARS-CoV-2 Nucleocapsid Antibody, Human IgG1 (AS95) (Cat. No. NUN-CH14) at 1μg/mL (100μL/well) can bind SARS-CoV-2 Nucleocapsid protein, His Tag (B.1.1.529/Omicron) (Cat. No. NUN-C52Ht) with a linear range of 0.4-6 ng/mL (Routinely tested).

  • 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.
