Are you ready for increased antibody testing demand?

Do you know someone who is wondering if they had COVID-19 and were asymptomatic? Are they thinking “Did I have COVID-19 and not realize it, was that short term cough due to allergies or did I have mild symptoms for COVID-19?”

As COVID-19 cases surge (see Johns Hopkins COVID-19 tracker), more people are questioning if they have been exposed to the SARS-CoV-2 virus. SARS-CoV-2 antibody testing provides evidence of past exposure to SARS-CoV-2 and the presence of potentially life saving or, at minimum, protective antibodies. If you haven't seen an increase in requests for antibody testing, don't be surprised if you do soon.

Are you or your partner labs ready for an influx of new SARS-CoV-2 antibody testing requests?

If you haven't implemented serological antibody testing in your lab or if you are looking for a backup testing option to meet upcoming demand, consider ZEUS's SARS-CoV-2 antibody offerings.

What Makes ZEUS Unique? The Dual Antigen Difference: Specificity Matters

The ZEUS ELISA SARS-CoV-2 Test Systems detect antibodies to TWO SARS-CoV-2 antigens - the highly immunogenic N-protein and the neutralizing spike receptor binding domain (S1-RBD) - to provide superior sensitivity and specificity.


ZEUS ELISA SARS - CoV-2 Antibody Test Systems Provide

  • Easy to use universal procedure for all kits
  • Fast turnaround time for results
  • Unique dual antigen approach
  • Accurate results with high specificity and sensitivity
  • Validated automation

The Dual Antigen Difference: Specificity Matters

Schematic labelled diagram of Coronavirus (SARS-CoV)2

S1-RBD: The surface glycoprotein of the virus, termed the spike (S) protein, mediates attachment of the virus to human cells via its receptor‐binding domain (RBD)1 and mediates fusion of viral and cellular membranes. Antibodies binding to the spike protein, and especially to the RBD domain, can neutralize SARS-CoV-2.

N-Protein: The nucleocapsid protein (N-protein) is the most abundant protein in coronavirus. The N-protein is a highly immunogenic phosphoprotein, and it is normally very conserved. The N protein of coronavirus is often used as a marker in diagnostic assays. 

During virion assembly, N protein binds to viral RNA and leads to formation of the helical nucleocapsid. The abundance and high hydrophilicity of N protein are supposed to contribute to potent immunity after coronavirus infection.

ZEUS’s dual antigen approach is unique as most available tests are limited to one or the other. By detecting antibodies directed against both the highly immunogenic N-protein and the neutralizing S1-RBD our assay is optimized for superior sensitivity and specificity.
