The effects of carbobenzyloxy-leucine-tyrosine-chloromethylketone (zLYCK), an inhibitor of chymotrypsin, were investigated on the activation pathways of the human neutrophil respiratory burst. At 10 microM zLYCK, a parallel inhibition was observed of superoxide production stimulated with the chemo-attractant FMLP and of

The preparation and optimization of a new monolithic chymotrypsin bioreactor for online protein digestion is described. Silica monolithic supports have been activated with epoxide functionalities following an optimized in situ procedure and used for covalent immobilization of chymotrypsin in one-step
