Methods of detecting an analyte in a sample are provided. In one embodiment, the method comprises forming a partition comprising the sample, a binding agent capable of emitting a signal when bound to the analyte, and a marker capable of identifying the partition; allowing the binding agent to bind to the analyte, if present; and detecting the presence of the analyte in the sample by detecting the signal emitted from the binding agent in the partition.
