Definition of unit
SCATU | 1 unit of Catalase equals to the amount of enzyme which decompose 1μmol of hydrogen peroxide to water and oxygen at 30°C and pH7.0 in 1 min. |
(*) Activity of the enzymes is expressed in SCATU/ml against an internal standard to ensure manufacturing lot-to-lot consistency. The enzyme activity value is not a measure for application performance. A detailed assay method is available upon request.

Safety
Enzyme preparations belong to protein, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
