Abstract Retroviral expression system which consists of retroviral vector, envelop protein vector and packaging cell line is an efficient expression system for recombinant protein. It has great potential in gene therapy and biopharmacy. Transcriptional active genome regions are the preferred targets for retrovirus integration. Furthermore, VSV-G protein enables this system a broader host range and makes virus integration more efficient.After infection of high-titer virus,high production clones can be selected through simple screening. So far, the research on retrovirus expression system has developed into application in bio-pharmacy industry. Here we introduce the composition of this system and the mechanism of virus transduction and summarize the application and prospect of retroviral expression system.
