Neutrophil elastase (human), (purified)

20-22 U/mg protein. One unit will hydrolyze 1.0 μmole of MeOSuc-Ala-Ala-Pro-Val-pNA (Prod. No. BML-P213) per minute, at 25°C in 100mM Tris-HCl, pH 7.5 with 500 mM NaCl.

As indicated on product label or CoA when stored as recommended. This enzyme is stable when stored under the above conditions. Procedures such as dilution of the enzyme followed by refreezing could lead to loss of activity.
