  • 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.
  • Application
    This product is intended for immunocapture, biopanning and flow cytometry. This product is produced non-sterile.
  • Reconstitution
    See Certificate of Analysis for details of reconstitution instruction and specific concentration.
  • Storage

    Upon receipt, please store the Beads at -20℃ for 1 year in lyophilized state.

    Please avoid more than 3 freeze-thaw cycles. Immediate use after reconstitution is highly recommended.

  • Assay Principles
    The Antigen pre-coupled magnetic beads are coupled with biotinylated protein onto streptavidin (SA) magnetic beads. Because Streptavidin (SA) has an extraordinarily high affinity for biotin with a dissociation constant (Kd) on the order of 10-14 mol/L, the biotinylated protein can bind to the SA beads irreversibly. We provide the SARS-CoV-2 nucleocapsid protein-coupled magnetic beads, which could help you to capture the antibody, and easily to follow up with other tests, such as immunocapture, biopanning and flow cytometry.

    Application Method:

    a) Reconstitute the Beads following the CoA, wash the Beads and suspended to a certain concentration by adding assay Buffer.

    b) Add your antibody to the beads, incubation and wash the beads.
