Single-chain antibodies neutralize activity and bind nonoverlapping
epitopes of botulinum A neurotoxin. Two phage display epitope libraries
were constructed from the 1.3 kb of binding domain cDNA. The minimal
epitopes selected against the single-chain Fv-Fc antibodies correspond
to conformational epitopes with amino acid residues 1115 to 1223 (S25), 1131 to 1264 (3D12), and 889 to 1294 (C25).
