Multiantigen IgG+IgA+IgM Assay is a multiplex, microsphere-based, highly sensitive and specific assay that measure the presence or absence of antibodies against four different SARS-CoV-2 antigens simultaneously.
Detecting SARS-CoV-2 neutralizing antibodies.
Identifying immune response after vaccination.
Identifying immune response to natural infection.
Identifying immune response to viral replication.
This serological bead-based assay has demonstrated to provide a wider range of information about the immune system response to SARS-CoV-2 than any other assay in the market, and it is performed in just 2 hours.
Single Receptor-binding domain of S-glycoprotein (RBD) coated beads.
Single stable trimer of the spicule glycoprotein (S) coated beads
Single Nucleocapsid protein (N) coated beads
Single Main virus protease or 3C-typeprotese (3CLpro,Mpro) coated beads.
Contains < 0.0014 % [w/w] reaction mass of CMIT/MIT (3:1).
Contains 10 % albumin in 10mM sodium phosphate, 150 mM NaCl, pH 7.4, contains KATHON anti-microbial agent.
Different serology tests detect antibodies to different parts of the virus, after vaccination the antibodies formed will only be to one part of the virus (the spike protein). To understand if vaccination stimulated an antibody response, a test specifically designed for the antibodies of interest would need to be used.
This test presents a great opportunity because it gives so much information about the immune response based on the detection of 3 types of immunoglobulins and 4 specific SARS-CoV-2 antigens simultaneously, allowing us to differentiate the immune response for clinical infection and vaccination.

The SARS-CoV-2 multiplex assay has been calibrated against the WHO First International Standard for Anti-SARS-CoV-2 Immunoglobulin (Human), NIBSC Code 20/136.
In this sense, it is possible to quantitatively report the concentration of IgG immunoglobulins in International Units (IU / ml) against RBD or in United Antibody Units (BAU / ml) against S, N and Mpro. For this reason, the kit includes a calibrator or standard of known concentration with which to make a calibration line through serial dilutions to each of the viral antigens used in the test (RBD, S, N, Mpro) in which to interpolate the fluorescence values resulting from the assay of the samples, thus obtaining the concentration in IU / ml or BAU / ml corresponding to each sample.
