  Methods and compositions are provided for analyzing in viable cells gene expression regulatory elements and systems. The method can be used to evaluate a transcriptional initiation regulatory system or the presence of a trans acting component. The method finds use in evaluating various transcriptional initiation functional sequences for use in expression of products, for the detection of trans acting agents associated with viruses and for quantitating the presence of infectious viruses. The method comprises introducing an expression cassette encoding an enzyme which has a fluorescent substrate, substantially irreversibly introducing the substrate into the cell host and detecting the formation of fluorescence during a predetermined time interval.

  The invention describes a method for the synthesis of compounds comprising the steps of: (a) compartmentalising two or more sets of primary compounds into microcapsules; such that a proportion of the microcapsules contains two or more compounds; and (b) forming secondary compounds in the microcapsules by chemical reactions between primary compounds from different sets; wherein one or both of steps (a) and (b) is performed under microfluidic control; preferably electronic microfluidic control. The invention further allows for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, and which is co-compartmentalised into the microcapsules.

  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.
