title: Activity-based fingerprinting and inhibitor discovery of cysteine proteases in a microarray.
abstract: A panel of 20 peptide vinyl sulfone probes has been synthesized and used to generate activity-based fingerprinting profiles of cysteine proteases in both gel- and microarray-based formats; the inhibitor fingerprints of representative small molecule inhibitors targeted against 4 cysteine proteases were also obtained, in high-throughput, using the same protein microarray platform.
