SARS-CoV-2 spike linear epitope scanning via a peptide microarray through sera profiling

Abstract

Summary: Host humoral immunological response plays an essential role in protection against pathogens. Identification of B-cell epitopes on antigens is required for accurate diagnosis and vaccine development. To map SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) spike linear epitopes, we developed a protocol of profiling sera from patients with COVID-19 (coronavirus disease 2019) via a peptide microarray designed according to spike protein. The protocol is also applicable for other antigens or sample types. This protocol is rapid, high throughput, and the cost is acceptable while it needs specialized microarray facilities.For complete details on the use and execution of this protocol, please refer to Li et al. (2020, 2021a, 2021b).
