Anti-SARS-CoV-2 IgG Test Kit

An immunoassay test intended for the detection of anti-SARS-CoV-2 IgG from serum or plasma from individuals.

CE/IVD Marked Product

Research Use Product

The QuantiVirus™ Anti-SARS-CoV-2 IgG Test is an immunoassay test intended for the detection of anti-SARS-CoV-2 IgG from serum or plasma from individuals suspected of COVID-19 by their healthcare provider. This test is to check if the COVID-19 virus antibody is present due to virus infection.

Looking for the RT-PCR test (nucleic acid test for viral RNA) to detect current infection with SARS-CoV-2?

How Does the QuantiVirus™ Anti-SARS-CoV-2 IgG Test Kit Work?

The QuantiVirus™ Anti-SARS-CoV-2 IgG Test is a two-step immunoassay using the Luminex MagPix® platform for the detection of anti-SARS-CoV-2 spike protein 1 (S1) RBD IgG antibody in human serum or plasma (EDTA) specimens. Recombinant spike protein 1 (S1) RBD is covalently coupled to the surface of MagPlex® Microspheres (also called “beads”) via a carbodiimide linkage.

First, S1 RBD coated beads and human specimens are mixed and incubated at room temperature for 1 hour, allowing the coated beads to capture the IgG antibodies present in human specimens.

After washing, Phycoerythrin (PE) conjugated anti-human IgG is added to reaction mixture and incubated at room temperature for 30 minutes.

After washing, PE fluorescence of each well in a 96-well plate is measured on Luminex MagPix® platform as Median Fluorescence Intensity (MFI).

Step 1

Capture beads and sample incubation at room temperature (1 hour)

Step 2

Anti-human IgG antibody incubation at room temperature (30 minutes)

Step 3

Plate reading & data acquisition
