Droplet-based assay system

System for performing a flow-based assay. The system may comprise a droplet generator to produce an emulsion including droplets in a carrier fluid. The system also may comprise a thermocycler including two or more temperature-controlled zones and also including a channel connected to the droplet generator for receiving the emulsion. The channel may form a single-pass continuous fluid route traversing the temperature-controlled zones multiple times, such that droplets passing through the channel are thermally cycled. The system further may comprise a detection station downstream from the thermocycler and configured to detect a signal from the droplets after such droplets have been thermally cycled by passing through the channel.
