| Abstract: | Highlights 1 A peptide Spep-1 targeting S2 of SARS-CoV-2 spike protein was selected by PhIP-Seq. 2 Spep-1 showed nanomolar affinity and high specificity to spike protein. 3 S-1 based immunoassay can detect femtomolar spike antigen in spiked serum samples. 4 Spep-1 can be used in future on S2 recognition, virus tracing and drug delivery. |
