Claims8
A method for producing a complex of a rare earth material-binding agent and a rare earth material, comprising:
- bringing the rare earth material-binding agent comprising a peptide capable of binding to the rare earth material into contact with the rare earth material to form the complex,
- wherein
- the rare earth material comprises at least one rare earth atom selected from the group consisting of lanthanum (La), lanthanum (La) ion, cerium (Ce), cerium (Ce) ion, neodymium (Nd), neodymium (Nd) ion, samarium (Sm), samarium (Sm) ion, gadolinium (Gd), gadolinium (Gd) ion, terbium (Tb), terbium (Tb) ion, dysprosium (Dy), dysprosium (Dy) ion, holmium (Ho), holmium (Ho) ion, erbium (Er), and erbium (Er) ion, and
- the peptide has an amino acid sequence represented by Leu-Trp-Gly-Asp/Glu-Val-Ser/Asn-Asp/Glu-Leu/Val-Asp/Glu-Phe/Leu-Leu.
