    摘要: The invention relates to a microfluidic platform and methods of using the platform for conducting enzyme assays using a droplet actuator. The enzyme assays of the invention are useful for, among other things, identifying and/or characterizing disorders resulting from conditions in which enzymes are defective or are produced in inappropriate amounts. Enzyme assays of the invention may, for example, be used to detect altered activity of a particular enzyme in a sample, which may serve as an indicator of a particular disease. Altered activity may, for example, be caused by conditions which result in the increased or reduced production of a certain enzyme or its substrate and/or conditions which result in defective enzymes and/or substrates exhibiting increased or decreased effectiveness relative to corresponding normal enzymes and/or substrates.

    摘要: The invention provides droplet actuators and droplet actuator techniques. Among other things, the droplet actuators and methods are useful for manipulating beads on a droplet actuator, such as conducting droplet operations using bead-containing droplets on a droplet actuator. For example, beads may be manipulated on a droplet actuator in the context of executing a sample preparation protocol and/or an assay protocol. An output of the methods of the invention may be beads prepared for execution of an assay protocol. Another output of the methods of the invention may be results of an assay protocol executed using beads. Among the methods described herein are methods of concentrating beads in droplets, methods of washing beads, methods of suspending beads, methods of separating beads, methods of localizing beads within a droplet, methods of forming emulsions in which droplets include beads, methods of loading beads into a droplet operations gap of a droplet actuator, methods of organizing beads in a monolayer, and methods of capturing, trapping or restraining beads.
