Screening and characterization of high affinity ZNP-binding peptide. a Amino acid sequences at the indicated positions (P1–P4) of peptides bound to ZNP were determined by mass spectrometry. b Relative affinities of selected peptides labeled with FITC were assessed by measuring fluorescent intensity of ZNP-peptide complexes. Error bars mean ± SD. c Detection of the interaction of a ZBP, FPYDGGDA, with ZNP by isothermal titration calorimetry (ITC)
