The activity of a cell surface protease, particularly an ADAM, is determined in a rapid and sensitive assay employing a whole cell system. The assays are effective to identify effector molecules that affect the activity of a cell surface protease directly or indirectly, and to screen for therapeutic agents that modulate those effector molecules. The assays can also be used to screen for therapeutic agents that modulate the activity of a cell surface protease associated with a disease or medical condition. Kits comprising at least one component of the present assays are also provided.

Whole cell assay systems for cell surface proteases

Cell based assays are performed in a microfluidic device, where the cells are introduced into a reservoir and are contacted with one or more agents prior to or during their residence in the reservoir or in a capillary channel connected to the reservoir. The cells are moved by electrokinesis individually from the reservoir to a detector, where the status of the cells as a result of contacting said agents is determined. Conditions are provided for moving the cells electrophoretically or by electroosmotic force, where the cells may be viable or fixed, natural or genetically modified.
