Anti-SARS-CoV-2 Spike ELISA

Designed to monitor with high specificity and sensitivity SARS-CoV-2 immune response.

Qualitative and quantitative assay

Detect antibodies generated as a response to SARS-CoV-2 natural infection and vaccination in the same assay.

Sars-CoV-2 ELISA Spike kit

Anti-SARS-CoV-2 Spike ELISA kit is a highly sensitive and specific test developed by Immunostep for the precise detection of either IgA/IgG antibodies against the Spike protein of the SARS-CoV-2. This kit is able to identify antibodies, both produced as response to natural infection, and to vaccination.

CE/IVD kits are only suitable for clinical use in European Union and countries with EU conformity recognition agreements. Manufactured in Spain by Immunostep under CSIC Patent Licence.

How are the antibodies quantified?

This ELISA kit against the S Protein has been calibrated against the WHO First International Standard for anti-SARS-CoV-2 immunoglobulin (human), NIBSC Code 20/136. In this way, it is possible to quantitatively report the concentration of IgA/IgG immunoglobulins in United Antibody Units (BAU / ml) against protein S. For this, the kit includes a positive control of known concentration with which to make a calibration line through serial dilutions.
