PROCESS FOR PRODUCING PEPTIDES BY USING IN VITRO TRANSCRIPTION/TRANSLATION SYSTEM

摘要

It is intended to construct a reaction system whereby a peptide produced in an in vitro peptide synthesis system can be efficiently isolated at a high puri ty from the reaction system, and, at the same time, to resolve the problem of t he consumption of energy in the reaction system. A process for producing a peptide or a peptide derivative by using a reaction system of transcribing a DNA into an RNA and then translating the RNA produced or a reaction system o f translating an RNA in vitro characterized in that a part or all of protein components constituting the transcription/ translation reaction system are labeled with one of a pair of substances adhering to each other and the othe r substance is used as an adsorbent for capturing said labeled protein components after translating.
