Figure 8. Comparison of viral neutralisation activity with monovalent and bivalent antibody formats.
Monovalent and bivalent versions of R1a-B6 (A) and R1a-A5 (B) were compared in neutralisation assays with laboratory adapted X-181 strain [corresponding to A/California/07/2009(H1N1)pdm09], NIBRG-14 [reverse genetics reassortant of A/Vietnam/1194/2004(H5N1)], NIBRG-91 [reverse genetics reassortant of A/chicken/Hong Kong/G9/97(H9N2)], NIBRG-109 [reverse genetics reassortant of A/New York/107/03(H7N2)] and NIBRG-147 [reverse genetics reassortant of A/Singapore/1/57(H2N2)]. Representative curves are shown and are the mean of two replicates. Antibody concentrations are in nM.
