An in vitro autogene

ACS Synth Biol. 2012 May 18;1(5):190-6. doi: 10.1021/sb3000113. Epub 2012 May 2.

Abstract

Recent technological advances have allowed development of increasingly complex systems for in vitro evolution. Here, we describe an in vitro autogene composed of a self-amplifying T7 RNA polymerase system. Functional autogene templates in cell-free lysate produce T7 RNA polymerase, which amplifies the autogene genetic information through a positive feedback architecture. Compartmentalization of individual templates within a water-in-oil emulsion links genotype and phenotype, allowing evolution.
