Representative proteolytic activity curves. (A) 520 nm QD DHLA-conjugate 4 assemblies were used to assay recombinant human caspase-3 activity under excess substrate conditions as described. Data from monitoring 580 nm QD DHLA-PEG600-conjugate 3 assemblies digested with human neutrophil elastase (B) or porcine pancreatic elastase (C), both in excess enzyme formats. Insets show a close-up of the initial activities at low enzyme concentrations. Estimated KM and Vmax values derived for caspase-3 are shown along with the Vmax. app. for the elastase assays.
