The phage-displayed-12 random dodecapeptide (Ph.D-12) library (New England Biolabs) was panned against D29-Fab-IgG to identify the antibody epitope as per instruction manual. The first round of panning was carried out with 100 mg/ml D29 Fab-IgG immobilized on Maxisorb Immunotube (Nunc). The amplified phage was enriched by three further rounds of panning in solution using Protein A or G sepharose in alternate rounds of panning. One round of negative selection with Protein A and G sepharose was carried out to minimize non-specific binders. The isolated peptide phage sequences were mapped against 3D protein structure using the Peptiope server with crystal structures of prM-E heterodimer at neutral pH (Protein Data Bank (PDB) accession code 3C6E). Graphic visualization was carried out using MSI WebLab ViewLite (Accelrys).
