    Binding of the sdAbs to the B-Victoria single residue mutant <t>HA0’s.</t> Candidate single residue mutations predicted to correlate with lineage-specific binding and a naturally occurring substitution H122Q, which differentiated between the B-Victoria and B-Yamagata strains, were generated and binding was tested using yeast display and flow cytometry. ( A ) Detection of the HA0 display level, using detection of the SV5 epitope tag attached to the HA0, showing that the mutations had no effect on the HA0 display level relative to the wild-type (wt) HA0 (indicated by vertical arrow). ( B ) Flow cytometry histograms showing binding of the Vic2a-6, Vic2a-20, Vic2b-3 and the YamNGS#1 to the wild-type HA (B/Brisbane/60/2008 precursor HA0) and selected mutants (the positive population is the right peak, whereas, the left peak shows the unbound and unstained populations). Mutations that completely eliminated sdAb binding are shown in red, those that partially affected binding are shown in orange and those that had no effect are shown in green. We determined the extent of sdAb binding by dividing the geometric mean fluorescence intensity (MFI) of each sdAb mutant pair by the value of the MFI of the wild-type B-Vic HA sdAb interaction and the resulting ratio, normalised to a percentage value of the wild-type interaction. Relative binding of the sdAbs was categorised as ‘no binding’ (in red)—

    Correlation of the sdAb epitopes with the Hemagglutinin structure. The structure of the HA0 monomer (B/Brisbane/60/2008 PDB structure 4FQM) is shown with the HA1 domain in blue, the stem region in grey, the 120 loop in yellow and the receptor binding site (RBS) in green. The residue of H122 and N129 associated with the B-Victoria lineage-specific binding of the sdAb Vic2a-6 or preferred binding of the Vic2a-20 are shown in red. The binding specificity of the sdAb panel are shown in relation to the HA head and stem region.

    ELISA showing sdAb binding to the recombinant hemagglutinin (HA0). sdAb binding to the recombinant HA0 from Influenza B-virus lineage representative strains used in immunisations and phage display library selections. B-Vic is B/Brisbane/60/2008, B-Yam is B/Florida/04/2006. Control sdAb A2c-3 is specific for influenza A hemagglutinin, PBS is a no sdAb negative control. ELISA signal is an average of 2 assays.
