Anti-SARS-CoV-2 Multiplex IgG+IgA+IgM
2.074,58 € excl.VAT
The SARS-CoV-2 multi-antigen IgG + IgA + IgM kit is a multiplex, bead-based immunoassay for the simultaneous and qualitative detection of specific IgG, IgM and IgA antibodies to 4 different antigens in SARS-CoV-2 array format by flow cytometry.
Each array bead has a unique fluorescence intensity pattern and is coated with a recombinant virus-specific antigen and allows antibodies binding present in human serum and plasma samples (K2-EDTA, K3-EDTA, Heparin-Li, Sodium Citrate). After incubation and subsequent washing with anti-human IgG, IgA and IgM antibodies conjugated with different fluorochromes (FITC, PE and PECyanine7), the samples are acquired in a flow cytometer.
The intended use of the assay is to assist in the identification of individuals with an adaptive immune response to SARS-CoV-2, indicating previous or recent infection and contributing, in combination with other tests (PCR or antigen), to the determination of the stage of infection. By testing several antigens and antibody classes at the same time, the assay can provide earlier and more sensitive results, contributing to its use in research, seroprevalence studies and epidemiological surveillance.
