  • Publication number: 20190113509
    Abstract: The present invention relates to a method for capturing a molecular target present in the aqueous phase of a water-in-oil emulsion, said method being based on the use of a binding system comprising (a) a surfactant bearing a functional moiety on its hydrophilic head group and (b) a chemoprobe that acts as a molecular staple between the functionalized surfactant and the molecular target and comprises at least two distinct domains namely (i) at least one capture moiety which is able to specifically bind the molecular target and (ii) at least one binding domain which is able to interact with the functional group of the surfactant through covalent or non-covalent interactions, directly or through a binding intermediary.

  • Publication number: 20190107489
    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, by 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 microcapsules; and identifying the compound which binds to or modulates the activity of the target. The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.

  • Publication number: 20190024261
    Abstract: The invention describes a method for the synthesis of compounds comprising the steps of: (a) compartmentalizing 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 reaction 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-compartmentalized into the microcapsules.

  • Publication number: 20180112212
    Abstract: The disclosure provides methods and compositions useful for labeling of target molecules with origin-specific nucleic acid identifiers (for example, barcodes), which can be used subsequently to identify, quantify, or otherwise characterize a feature or activity of target molecules originating from a particular discreet volume. Such target molecules can include polypeptides expressed by cells, in which nucleic acid molecules encoding the polypeptides are labeled with the same, or matched, origin-specific nucleic acid identifiers.
