Although human antibodies elicited by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid (N) protein are profoundly boosted upon infection, little is … identify CD8+ T cells specific for a conserved and immunodominant SARS-CoV-2 epitope in HLA-B7+ individuals. The pandemic caused by SARS-CoV-2 is a public health emergency of international concern. Blood tests to detect antibodies against SARS-CoV-2, the virus that causes COVID-19, are an important tool for diagnosing the disease, developing potential treatments, and … Blood tests to detect antibodies against SARS-CoV-2, the virus that causes COVID-19, are an important tool for diagnosing the disease, developing potential treatments, and … Ortho's new VITROS ® Anti-SARS-CoV-2 Total Nucleocapsid Antibody Test is a highly accurate 4 test for the qualitative detection of SARS-CoV-2 nucleocapsid antibodies … A team of scientists recently investigated and compared the efficacy of spike-based and nucleocapsid-based COVID-19 vaccines in mice infected with SARS-CoV-2. The impact of seasonal coronaviruses on immune responses to SARS-CoV-2 is an active area of research. Two enzyme-linked immunosorbent assay (ELISA) kits based on recombinant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid protein (rN) and spike protein (rS) were used for detecting IgM and IgG antibodies, and their diagnostic feasibility was evaluated. They were all tested additionally for IgG anti-Nucleocapsid antibodies, the COVID-specific antibodies, to see if they were infected. Technical information about specificity and sensitivity, cross-reactivity, neutralizing potential, and their validated applications are illustrated here. Evaluation of Nucleocapsid and Spike Protein-Based Enzyme-Linked Immunosorbent Assays for Detecting Antibodies against SARS-CoV-2 J Clin Microbiol.
