Abstract: The invention generally relates to performing sandwich assays in droplets. In certain embodiments, the invention provides methods for detecting a target analyte that involve forming a compartmentalized portion of fluid including a portion of a sample suspected of containing a target analyte and a sample identifier, a first binding agent having a target identifier, and a second binding agent specific to the target analyte under conditions that produce a complex of the first and second binding agents with the target analyte, separating the complexes, and detecting the complexes, thereby detecting the target analyte.

Abstract: The invention generally relates to methods for quantifying an amount of enzyme molecules. Systems and methods of the invention are provided for measuring an amount of target by forming a plurality of fluid partitions, a subset of which include the target, performing an enzyme-catalyzed reaction in the subset, and detecting the number of partitions in the subset. The amount of target can be determined based on the detected number.
