    摘要: The invention provides a method of redistributing magnetically responsive beads in a droplet. The method may include providing a droplet including magnetically responsive beads. The droplet may be provided within a region of a magnetic field having sufficient strength to attract the magnetically responsive beads to an edge of the droplet or towards an edge of the droplet, or otherwise regionalize or aggregate beads within the droplet. The method may also include conducting on a droplet operations surface one or more droplet operations using the droplet without removing the magnetically responsive beads from the region of the magnetic field. The droplet operations may in some cases be electrode-mediated. The droplet operations may redistribute and/or circulate the magnetically responsive beads within the droplet. In some cases, the droplet may include a sample droplet may include a target analyte. The redistributing of the magnetically responsive beads may cause target analyte to bind to the magnetically responsive beads. In some cases, the droplet may include unbound substances in a wash buffer. The redistributing of the magnetically responsive beads causes unbound substances to be freed from interstices of an aggregated set or subset of the magnetically responsive beads.

    摘要: The present invention provides for the detection of cardiac markers on a droplet actuator. An aspect provides a method of assaying a cardiac marker in a biological sample from a subject, the method including providing a droplet actuator, loading the biological sample and assay reagents on the droplet actuator, executing droplet operations to create sample droplets from the sample and reagent droplets from the reagents on the droplet actuator, and executing droplet operations using the sample droplets and reagent droplets to produce a detectable signal indicative of the quantity of the cardiac marker in the biological sample. Still other aspects are provided.
