The Bio-Plex Pro Human IgG SARS-CoV-2 S1/S2/N/RBD 4-Plex Panel detects IgG antibodies against SARS-CoV-2 nucleocapsid, receptor-binding domain, spike 1, and spike 2 viral antigens. Measuring antibodies against each SARS-CoV-2 viral protein enables researchers to study the immune response to natural infection, vaccination, and levels of exposure in populations.

Features and Benefits

  • Comprehensive panel coverage — detects antibody response to four highly relevant SARS-CoV-2 viral antigens in a single well
  • High specificity and sensitivity  builds greater confidence in a positive or negative assessment in samples for seroprevalence studies
  • Fast protocol — results in less than 3 hours
  • Reproducibility — attain consistent results in your experiments with a robust, magnetic bead-based workflow
  • Streamlined data analysis — manage and analyze your data with ease using Bio-Plex Manager and Bio-Plex Data Pro Software

Kit Components

  • Magnetic capture beads coupled with SARS-CoV-2 viral antigens:
    • Nucleocapsid protein
    • Receptor-binding domain (RBD) protein subunit
    • Spike 1 protein subunit
    • Spike 2 protein subunit
  • Anti-human IgG detection antibody
  • Ready-to-use positive and negative controls
  • Wash buffer and assay buffer
  • Sample and detection antibody diluents
  • Streptavidin-PE
  • 96-well flat-bottom plate and sealing tape

Individual kit components can also be purchased to create custom assays.
