Principle of the Assay

The Q-Plex SARS-CoV-2 Human IgG (5-Plex) array simultaneously recognizes human IgG antibodies to S1 and S2 subunits of the spike glycoprotein as well as antibodies specific for the nucleocapsid protein (NP). Whereas the spike glycoprotein is crucial for the virus’ ability to attach to a cell, the NP is the primary protein that makes up the shell, or capsid, of the virus. The assay also detects antibodies towards the Fc region of sheep antibody to control for cross-reactivity between sample and the assay components. Finally, the kit uses detection of anti-human IgG as a positive control to ensure the assay performs to expectations.

Kit Content

Each kit contains a 96-well plate, featuring the relevant biomarker panel in each well, and all reagents required to perform testing.

Reagents Include:

  • Detection Mix
  • Calibrators (High, Low, Negative)
  • Substrate
  • Sample Diluents
  • Streptavidin HRP
  • Wash Buffer


All Quansys Q-Plex™ Multiplex and Singleplex assays require the use of the Q-View™ Software to read and interpret the test results. A fully-functional, free trial version of the software is available to download, install, and use to analyze your first kit(s). At the end of the trial period, a purchased license is required to continue the use of the Q-View software.

Q-Plex™ Arrays are developed and optimized to work with Q-View™ Imagers. Quansys does not guarantee the results obtained from other imagers and not all imagers are compatible with Quansys Q-Plex Arrays.
