Abstract: Methods for screening a compound for enzyme inhibition activity include providing at least one sample mixture to a microfluidic device, applying vacuum pressure to the sample mixture, flowing the sample mixture along a microchannel of the microfluidic device, separating at least two components of the sample mixture based upon a net charge difference between the product and at least one other material to produce separated material, detecting at least one of the separated materials, and determining enzyme inhibition activity based on the detection of the separated material. Kits for screening a compound for enzyme inhibition activity include a first multiwell plate having a specific plurality of enzymes disposed within a first plurality of wells and a second multiwell plate having a plurality of enzyme substrates disposed with a second plurality of wells, a phosphate source and a cofactor disposed within each well of the second plate.

Abstract: The present invention provides a system for conveying a moving status of a motorized vehicle. The system includes a decelerating device operable to slow down the motorized vehicle; a measuring device electrically coupled to the decelerating device to measure an instantaneous speed of said motorized vehicle at a time the decelerating device is activated; and a displaying device electrically coupled to the measuring device to display the instantaneous speed to an object behind the motorized vehicle.
