Compartmentalised self replication method for in vitro evolution of molecular libraries
First Claim
1. A method of selecting an active nucleic acid replicase, the method comprising the steps of:
- (a) providing a pool of nucleic acids comprising nucleic acid members each encoding a nucleic acid replicase;
(b) subdividing the pool of nucleic acids into compartments, such that each compartment comprises a nucleic acid member and the contents of each compartment are not in contact with the contents of other compartments;
(c) expressing the nucleic acid member in the compartment to form the nucleic acid replicase encoded by said nucleic acid member;
(d) providing conditions within the compartment under which the nucleic acid member may be processed by the nucleic acid replicase encoded by said nucleic acid member; and
(e) detecting processing of the nucleic acid member by the nucleic acid replicase encoded by said nucleic acid member, whereby an active nucleic acid replicase is selected.

Abstract
We describe a method of selecting an enzyme having replicase activity, the method comprising the steps of: (a) providing a pool of nucleic acids comprising members each encoding a replicase or a variant of the replicase; (b) subdividing the pool of nucleic acids into compartments, such that each compartment comprises a nucleic acid member of the pool together with the replicase or variant encoded by the nucleic acid member; (c) allowing nucleic acid replication to occur; and (d) detecting amplification of the nucleic acid member by the replicase. Methods for selecting agents capable of modulating replicase activity, and for selecting interacting polypeptides are also disclosed.
