Semliki Forest Virus Expression System

Eukaryotic cells can be programmed to synthesize foreign proteins by infection with recombinant Semliki Forest virus. The foreign protein is produced at a high level from about 4 h after infection, whereas cell-derived protein synthesis is shut down.

Keywords: mammalian protein expression; biotechnology
