Abstract:
We screened a phage display peptide library for peptidyl mimotopes of gibberellin against anti-bioactive gibberellin antibody. The peptides obtained were grouped into two homologous sequences and their binding to the antibody was put in competition with free GA(4) but not with GA(4) methylester, suggesting that the peptides behave as mimics of GA(4). As an application, the phage display peptide was shown to work as a tracer for enzyme-linked immunosorbent assay (ELISA) analysis of GA(4).
