Abstract:
1. A method of resuspending magnetically responsive beads between wash cycles, the method comprising: (a) providing a droplet actuator comprising: (b) positioning a droplet having magnetically responsive beads suspended therein at a location at least partially overlapping the first region of the magnetic field, wherein at least a portion of the magnetically responsive beads become unsuspended; (c) transporting the droplet through activation of selected droplet operations electrodes away from the first region of the magnetic field without removing the magnet; (d) transporting the droplet through activation of selected droplet operations electrodes towards the first region of the magnetic field; and (e) repeating steps (b) and (c) to cause sufficient resuspension of beads such that unbound material may be effectively removed in subsequent wash cycles.
