Abstract
A method for producing a ribosome display complex includes obtaining a ribosome complex including an unmodified polypeptide chain, an mRNA molecule and a ribosome by initiating translation of the mRNA molecule in a cell-free peptide synthesis system including the ribosome, and modifying the unmodified polypeptide chain by reacting a side chain reactive functional group in the unmodified polypeptide chain with a modifying reagent to produce a ribosome display complex including a modified polypeptide chain, the mRNA molecule and the ribosome. The unmodified polypeptide chain includes at least one reactive amino acid residue selected from the group consisting of a cysteine residue, a lysine residue, a histidine residue and a tryptophan residue. The at least one reactive amino acid residue includes the side chain reactive functional group, and the mRNA molecule includes a base sequence encoding an amino acid sequence of the polypeptide chain.
