iQue® SARS-CoV-2 (IgG, IgM, and IgA) kit for COVID-19 research

Using the iQue® SARS-CoV-2 (IgG, IgM and IgA) Kit, users are able to explore COVID-19 research and obtain a comprehensive profile for SARS-CoV-2 using a multiplex and high-throughput serological assay. This kit from Sartorius allows for the qualitative and quantitative analysis of anti-SARS-CoV-2 Spike RBD antibodies from human blood samples (sera and plasma) using a simple workflow that is designed with user-friendliness in mind.

Top features of the iQue® SARS-CoV-2 (IgG, IgM and IgA) kit

  • Integrated detection of all three antibody isotypes helps save time and valuable samples
  • Precise immune response assessment
  • High throughput and simplified analysis can be performed for SARS-CoV-2 serological surveillance

Popular applications for the iQue® SARS-CoV-2 (IgG, IgM and IgA) kit

  • Immunology
  • Vaccine development
  • Virology research


The outbreak of SARS-CoV-2 continues to persist as a result of its ability to constantly mutate and evade immunization. Protection against the virus is thus dependent on the development of a humoral immune response, which means that there is still an ongoing need for the accurate assessment of quantity and duration of antibody response (particularly those targeting the SARS-CoV-2 spike protein receptor binding domain).

To facilitate characterization and monitor the duration of the antibody response in both COVID-19 patients and vaccinated individuals, detect asymptomatic infections and survey past infection prevalence in a population, serological testing to quantitate the three major isotypes (IgG, IgM and IgA) of antibodies specific for SARS-CoV-2 Spike RBD can be used.

With the help of the iQue® SARS-CoV-2 (IgM, IgG, and IgA) Kit, detection is quick and trustworthy.

Innovation for smarter research

While it is possible to identify anti-SARS-CoV-2 Spike RBD IgG, IgM, or IgA antibodies using conventional enzyme-linked immunosorbent assay (ELISA), flow cytometry, and lateral flow immunoassay, these techniques have drawbacks:

  • Provide only qualitative results
  • Labor-intensive and do not support applications with high throughput
  • Requires massive amounts of reagents
  • IgG, IgM, and IgA antibody multiplexing analysis is not permitted

The iQue® SARS-CoV-2 (IgG, IgM, and IgA) kit offers a quick, strong, and sensitive serological assay for measuring IgM, IgG, and IgA anti-SARS-CoV-2 Spike RBD antibodies and is available in a single well of a 96- or 384-well plate along with antibody detection levels in the pg/mL range.

Maximized productivity

The multiplexed assay allows for the high-throughput analysis of the three major isotypes (IgG, IgM and IgA) of antibodies specific for SARS-CoV-2 Spike RBD in a single well for a comprehensive analysis of the immune response.

Save precious samples

Users can preserve laboratory samples by using a streamlined workflow that only requires a single 10 µL sample diluted at a minimum of 100-fold. Sartorius' kit enables users to obtain reliable and accurate data without exhausting valuable resources like reagents.
