SARS-CoV-2, the causative viral agent of the disease COVID-19, is a coronavirus which bears the transmembrane glycoprotein spikes (S protein) typical of viruses in its clade. These spikes are a prominent target of human immune responses and have been found to be highly immunogenic. The receptor-binding domain (RBD) of the S protein is particularly targeted by neutralising antibodies. The spikes on SARS-CoV-2 allows the virus to enter host cells through the human receptor angiotensin converting enzyme 2 (ACE2), present in alveolar epithelial cells.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to the target protein. Standards or samples are added to the micro ELISA plate wells and bind to the immobilized antibody. A biotinylated detection antibody specific to the target protein is then added, followed by Avidin-Horseradish Peroxidase (HRP) conjugate. Free components are washed away. The substrate solution is added to each well, resulting in a color change. Only wells containing the target protein, detection antibody, and HRP conjugate will develop a blue color. The reaction is terminated by the addition of stop solution, resulting in a yellow color. The optical density (OD) is measured at 450 nm ± 2 nm. The OD value is directly proportional to the concentration of the target protein in the sample and is determined using a standard curve.
