Patent attributes
The invention provides systems, methods, reagents, apparatuses, vectors, and host cells for the continuous evolution of nucleic acids. For example, a lagoon is provided in which a population of viral vectors comprising a gene of interest replicates in a stream of host cells, wherein the viral vectors lack a gene encoding a protein required for the generation of infectious viral particles, and wherein that gene is expressed in the host cells under the control of a conditional promoter, the activity of which depends on a function of the gene of interest to be evolved. Some aspects of this invention provide evolved products obtained from continuous evolution procedures described herein. Kits containing materials for continuous evolution are also provided.
