The ZEUS smart automation solution for SARS-CoV-2 antibody testing

Mar 16, 2021

Two Antigens = Twice the Confidence

Now is the perfect time to partner with ZEUS Scientific for your SARS-CoV-2 antibody testing, and put the power of our dual antigen design to work in your laboratory with full automation right out of the box.

The power of combining the ZEUS ELISA SARS-CoV-2 Antibody Test Systems and the Dynex AGILITY® fully automated ELISA system is in the details. The ZEUS ELISA SARS-CoV-2 Test Systems contains antigens to both the SARS-CoV-2 Nucleocapsid protein and Spike protein (S1-RBD) on the ELISA plate. The combination of both antigens demonstrated excellent assay sensitivity and specificity in the detection of antibodies in serum and plasma. This design also allows for detection of antibodies produced by a natural SARS-CoV-2 infection and/or from vaccination. Both the ZEUS ELISA SARS -CoV-2 IgG and Total (IgG, IgM, IgA) Antibody Test Systems follow the ZEUS universal ELISA assay protocol for easy incorporation with your existing test menu and are provided in SmartKit® Gold packaging for easy loading onto the Dynex AGILITY® System.

The combination of the ZEUS unique dual antigen design, SmartKit® Gold packaging and the Dynex AGILITY® fully automated ELISA System provides faster results reporting, increased productivity and frees up your laboratory personnel with a throughput that meets all laboratory requirements. This is the ZEUS smart solution for your SARS-CoV-2 antibody testing.

  • Unique ZEUS dual antigen assay design recognizes antibodies to both the N-protein and the S1-RBD proteins of SARS-CoV-2, allowing for detection of antibodies produced by a natural SARS-CoV-2 infection and/or from vaccination.
  • Simple direct loading with SmartKit® Gold Packaging reduces costs associated with disposable plastics and avoids data entry errors, ultimately saving technician’s time.
  • High throughput (up to 810 reportable results/8 hours) provides fast results in formats that fit the laboratory’s needs.
  • Traceability with 2D Barcoding throughout the workflow eliminates transcription errors and adds confidence to your results.

 

The ZEUS ELISA SARS-CoV-2 IgG Test System has FDA Emergency Use Authorization for the qualitative detection of IgG antibodies to SARS-CoV-2 virus in human serum and plasma and includes automated processing on the Dynex AGILITY® automated ELISA System. The Agility offers high throughput and takes advantage of the SmartKit® Gold packaging, providing the ability to fully automate the procedure from sample to result in a throughput meeting all laboratory requirements.

The ZEUS ELISA SARS-CoV-2 Total (IgG, IgM, IgA) Antibody Test System has been validated per FDA EUA guidelines and submitted to the FDA. Both ZEUS ELISA products are available today.

Test with Confidence. Test with ZEUS.

 

The Dual Antigen Difference: Specificity Matters

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. 

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. Also by design our assay will detect antibody produced by a natural SARS-CoV-2 infection and/or vaccination.
