Screening the NDV-specific nanobodies from the VHH library. a Titers of antibodies against NDV particles in the sera from the camel after the fifth immunisation. b Detection of the periplasmic extracts from 96 clones reacting with NDV particles with indirect ELISA. c Alignment of amino acid sequence of 13 screened nanobodies. Numbering and CDRs according to previous methods. The residues at positions 37, 44, 45, and 47 are indicated by red arrows. d Titration of the 13 screened nanobodies in the periplasmic extracts binding with NDV
