Post-Genome Institute

Post-Genome Institute (PGI) is a Japanese biotechnology company specializing in the development of cell-free protein synthesis and genomic analysis platforms. The company is best known for its PUREsystem™, a reconstituted in vitro transcription/translation system that uses only purified recombinant elements from E. coli to produce proteins with high speed and precision. This platform is particularly valuable for synthesizing proteins that are toxic to living cells or require strictly controlled conditions. PGI also provides the IniTIA technology for high-resolution analysis of mRNA transcription initiation sites, aiding in the identification of disease-specific variants. Through a strategic partnership with New England Biolabs, PGI's core technology is distributed globally as PURExpress™, supporting research in synthetic biology and drug discovery. The company continues to offer customized protein production services and specialized kits to the international life sciences community.
