Microfluidic in-line labeling method of continuous-flow protease inhibition analysis

---

Abstract

---

Enzyme assays are performed in microfluidic devices including, e.g., in-line labeling, separation, and detection of assay products. In-line labeling allows assays, e.g., protease assays, to be performed in a continuous flow microfluidic format. Also included are microfluidic devices and integrated systems for performing in-line labeling in continuous flow enzyme assays.
