• Anti-SARS-Cov-2 Multiplex Serology Assay: one of the most sensitive and reliable SARS-CoV-2 assays coming soon

  • Flow cytometry SARS-CoV-2 multiantigen test simultaneously target four separate SARS-Cov-2 specific antigens

  • we are working every day to open opportunities for a better understanding of the immune response and its evolution over time after vaccination. 

SARS-CoV-2 Multiantigen IgG+IgA+IgM kits

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. 

Spike Protein

Identifying immune response after vaccination.


Identifying immune response to natural infection.

RBD Domain 

Detecting SARS-CoV-2  neutralizing antibodies.


Identifying immune response to viral replication.

    Information for Laboratories and Distributors:

    I have read the terms and conditions of the Privacy Policy and accept the terms.

    Qualitative  and quantitative analysis of the inmune response.

    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.

    Accurately differentiating Immune Response by Virus Infection and Vaccination.
