Kallikrein in human urine was measured using a fluorogenic peptide substrate, proly-phenyl-alanyl-arginine-4-methylcoumaryl-7-amide (Pro-Phe-Arg-MCA). Using 20 microliters of normal urine, kallikrein activity was quantitatively assayed by incubation with a final concentration of 10(-4) M Pro-Phe-Arg-MCA at 37 degrees C for 90
