Fig. 3From: Screening and purification of nanobodies from E. coli culture supernatants using the hemolysin secretion systemAmino acid sequence of VHHs clones identified after Hly-screening. Alignment of the amino acid sequences of the VHH domain in the clones selected by Hly-screening. The CDRs are labelled in colours: CDR1 (red), CDR2 (blue) and CDR3 (green). Cysteine residues are highlighted in yellowBack to article page
