Compartmentalised screening by microfluidic control
First Claim
1. A method for screening a repertoire of compounds for a compound having a desired activity, comprising the steps of:
- (a) providing an aqueous fluid comprising the repertoire of compounds;
(b) compartmentalising the repertoire of compounds into microcapsules by partitioning the aqueous fluid with an immiscible fluid as the aqueous fluid is flowing through a microfluidic channel, such that only a subset of the repertoire is represented in multiple copies in any one microcapsule and wherein each microcapsule comprises a target cell;
(c) conducting a reaction involving a molecule associated with the target cell, wherein the compound has an effect on the reaction; and
(d) detecting a product of the reaction to identify a microcapsule containing the compound having the desired activity.

Abstract
The invention describes a method for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, comprising the steps of: a) compartmentalizing the compounds into microcapsules together with the target, such that only a subset of the repertoire is represented in multiple copies in any one microcapsule; and b) identifying the compound which binds to or modulates the activity of the target; wherein at least one step is performed under microfluidic control. The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.
