Acid hydrolases in blister fluid. 3. Characterization and quantification of peptide hydrolases.

Cathepsin B1 and Cathepsin C have been characterized and quantified in suction blister fluid. These enzymes revealed practically no activity in interstitial fluid and serum. Arylamidase was also investigated and found to have similar concentrations in serum, blister fluid and interstitial fluid. The properties of arylamidase from these sources were identical.
