| Abstract |
Virus particles are used in vaccination, drug delivery, and material sciences. Here we devised a system where the RNA virus encephalomyocarditis virus (EMCV) is synthesized from DNA templates in vitro. When a plasmid or a PCR product harboring the full-length cDNA of EMCV in the T7 promoter/terminator unit was incubated in a HeLa cell extract supplemented with T7 RNA polymerase, EMCV was produced within 4 h at an efficiency of over 10-fold compared with the system programmed with the EMCV RNA. The EMCV RNA transcribed by the virally encoded RNA-dependent RNA polymerase was predominantly incorporated into the EMCV particle even in the presence of a larger amount of the EMCV RNA transcribed by T7 RNA polymerase from the plasmid. |
