(1) Peptidase Activity (synthetic substrate method)

The sample solution is warmed at 37°C with the synthetic chromogenic substrate S-2251 (H-D-valyl-L-leucyl-L-lysine-p-nitroanilide dihydrochloride) as a substrate and the absorbance at 405nm is determined. The enzyme activity is defined as 1 unit when 1nmol of p-nitroaniline per minute is released.
(2) Bacillus subtilis natto-produced Protein (ELISA)

ELISA (enzyme-linked immunosorbent assay) uses rabbit-specific antibodies to the Bacillus subtilis natto-produced protein, responsible for the peptidase activity, to measure the amount of antigen reacting with the specific antibodies.
