Blitz binding data. Levels of binding to (A) CPV or (B) FPV capsids of wild-type scFv of Fab 14 or scFv14 variants with mutations in the complementarity-determining region. Protein A biolayer interferometry probes were incubated with scFv-Fc to the same level of bound protein, washed, incubated with CPV-2 or FPV empty capsids, and then incubated in buffer. Mutant scFv14 forms were Ser50Gly and Asn53Gly together, Gly316Ala alone, or all three mutations.
