Unit definition: 

*Endotoxin: Ph. Eur. (1 Endotoxin Unit is equal to 1 International Unit of a WHO approved reference standard endotoxin (RSE)).

**PZ Unit (acc. to Wünsch2): 
1 U according to Wünsch catalyzes the hydrolysis of 1 µmol 4-phenylazobenzyloxycarbonyl-L-prolyl-L-leucylglycyl-L-prolyl-D-arginine per minute at 25 °C, pH 7.1.

***Neutral Protease: 
1 DMC Unit catalyzes the cleavage of 1 µmol peptide bond from dimethylcasein per minute at 25 °C, pH 7.0, expressed in terms of newly formed terminal amino groups, determined with TNBS.3
