Fig. 2From: Identification of COVID-19 B-cell epitopes with phage-displayed peptide libraryIdentified peptides from COVID19 positive reacted phage clones. a A phage-displayed random peptide library was screened with serum antibodies from patient AS1 and AS3, respectively. After three screening rounds, enriched phage clones were significantly reactive to antibodies in serum samples from COVID-19 patient but not to samples of normal human serum (NHS). b, c Alignment analysis of sequenced peptides from AS1 (b) and AS3 (c) biopanning was conducted, and identified the conserved residues corresponding to SARS-CoV-2 viral proteinsBack to article page
