SARS-CoV-2, a single stranded RNA virus, has quickly become the subject of much research worldwide. Coronaviruses are composed of four primary proteins: the spike (S), envelope (E), membrane (M), and nucleocapsid (N). The spike protein (S-protein) performs two primary tasks that aid in host infection: 1) mediates the attachment between the virus and host cell surface receptors such as ACE2, and 2) facilitates viral entry into the host cell by assisting in the fusion of the viral and host cell membranes. In December of 2020 three new SARS-CoV-2 variants came to light, UK B.1.1.7, South Africa B.1.351 and Brazil P.1/P.2.
Eagle Biosciences offers a SARS CoV-2 Spike Protein Antigen Quantitative ELISA Assay Kit that is highly sensitive. Clinical studies show that this kit is effective at detecting the spike protein antigen in all three major circulating SARS-CoV-2 variant strains. Click here to learn more.
