    摘要: In certain embodiments, provided are methods and compositions useful for the detection and quantitation of catalytically active enzymes, particularly catalytically active proteases. The compositions comprise one or more multifunctional tags, wherein each different multifunctional tag comprises a different mobility modifier, a partitioner, a reporter, and a peptide substrate that is specifically or substantially specifically hydrolyzed by a target protease or target protease family. Hydrolysis of each different multifunctional tag by a target protease provides a different labeled hydrolytic product comprising a reporter and a mobility modifier but not a partitioner, where the mobility modifier confers a distinctive mobility on the labeled hydrolytic product in a mobility-dependent analysis technique.
