Patent ID: 10676729

Abstract:
Provided are compositions, e.g., multiplexed platforms or systems, to screen for molecules, e.g., small molecule active agents such as drugs, that inhibit enzymes such as proteases. Provided are cell-based or multiplexed platforms for monitoring or assay the activity of a protease. Provided are cell-based assays and multiplexed systems for the monitoring of enzyme, activity such as proteolytic cleavage on the cell surface, where optionally the protein, e.g., an enzyme, can be naturally expressed on the cell surface or engineered to be expressed on the cell's surface. Provided are cells and stable cell lines expressing an “assay construct” and an enzyme of interest, where optionally one cell or cell line expresses both the “assay construct” and the enzyme, or two different cells or independent cell lines are used and mixed in the assay, where one expresses the “assay construct” with the enzyme substrate and the second expressing the enzyme.
