Fig. 2From: Construction of a camelid VHH yeast two-hybrid library and the selection of VHH against haemagglutinin-neuraminidase protein of the Newcastle disease virusDeduced amino acid alignment of 7 selected anti-HN VHH. Deduced amino acid sequences were analyzed according to the Kabat numbering [54]. The dots indicate the same sequences compared with VHH1. Differences in the sequences are pinked, and the dash represent the missing sequences. Two hallmark Cys residues are labeled by the thick-line boxes. The four conservative hallmark residues of VHH in FR2 are labeled by the dotted line boxesBack to article page
