Simple, efficientin vitrosynthesis of capped RNA useful for direct expression of cloned eukaryoti genes

Abstract
A simple and efficient method for direct in. vitro synthesis of capped transcripts of cloned eukaryotic genes is described. As an example capped transcripts were made from a plasmid containing the human fibroblast interferon gene cloned under the control of a prokaryotic promoter. These transcripts were translated in vivo in Xenopus laevis oocytes and in vitro in reticulocyte and in wfieat germ cell-free protein synthesizing systems.
