    摘要: A method of conducting a droplet-based enzymatic assay is provided. The method generally makes use of a droplet actuator. A droplet comprising an enzyme of interest is provided on the droplet actuator along with a droplet comprising a substrate which is potentially modified in the presence of the enzyme. The method involves executing droplet operations on the droplet actuator to combine the droplets, thereby yielding an assay droplet, and detecting modification of the substrate by the enzyme in the assay droplet on the droplet actuator. The enzyme of interest may, for example, be a potentially mutated or improperly folded enzyme exhibiting altered enzyme activity as compared to a corresponding normal enzyme.

    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.
