Using 6mer and 12mer phage peptide libraries three unique phage clones were identified which specifically bind to a monoclonal anti‐FITC antibody, B13‐DE1. The two 6mer and one 12mer peptide insert sequences are clearly related to each other and contain a high proportion of hydrophobic amino acids. The peptides are bound by the antibody combining site of B13‐DE1 probably in a similar manner to FITC and represent therefore true peptidic mimics of the fluorescein hapten. No reactivity of the peptides could be demonstrated with another monoclonal anti‐fluorescein antibody or with polyclonal anti‐fluorescein antibodies. Immunization of mice with the peptides resulted in the production of antibodies cross‐reacting with all peptides but not with fluorescein. The results show that phage peptide libraries can be used to isolate mimotope peptides which can mimic low molecular weight structures seen by a specific antibody and probably other recognition molecules.
