Abstract
The invention describes a method for isolating one or more genetic elements encoding a gene product having a desired activity, comprising the steps of: (a) compartmentalising genetic elements into microcapsules; and (b) sorting the genetic elements which express the gene product having the desired activity; wherein at least one step is under microfluidic control. The invention enables the in vitro evolution of nucleic acids and proteins by repeated mutagenesis and iterative applications of the method of the invention.
Claims5
A method for isolating one or more genetic elements encoding a gene product having a desired activity, comprising the steps of:
- providing one or more genetic elements;
- compartmentalising the genetic elements into a microcapsule by forming a water-in-fluorocarbon or water-in-perfluorocarbon emulsion microcapsule within a microfluidic device;
- expressing the genetic elements to produce their respective gene products within the microcapsules;
- and
- sorting the genetic elements which express gene product(s) having the desired activity;
- wherein the method is under microfluidic control.
