Development of an isotope-coded activity-based probe for the quantitative profiling of cysteine proteases

Bioorg Med Chem Lett. 2004 Jun 21;14(12):3131-4. doi: 10.1016/j.bmcl.2004.04.046.


Quantification studies of complex protein mixtures have been restricted mainly to whole cell extracts. Here we describe the synthesis of two sets of isotope-coded activity-based probes that allow quantitative functional proteomics experiments on the cathepsins.
