As indicated on product label or CoA when stored as recommended. Stored at -20°C this product is stable for years.Storage of the reconstituted form at 4°C for 2 weeks has no effect on enzyme activity. If solutions must be stored for extended periods of time, protein concentration should be kept above 1mg/ml and the activity should be determined prior to use. Freezing solutions of Myeloperoxidase may cause substantial loss of activity.

Reconstitution of 25 μg with 100 μl distilled water gives approximately 3.45μM calculated with a molar extinction coefficient of 91.000 M-1cm-1. per hem at 429nm.
