Another commonly used unit of activity is the KIU (Kallikrein Inhibitor Unit).
1 TIU ∼ 1,300 KIU.
Protein determined by biuret.
Contains 5-10 TIU per mL solution.
One trypsin inhibitor unit (TIU) will decrease the activity of 2 trypsin units by 50% where one trypsin unit will hydrolyze 1.0 μmole of N-α-benzoyl-
Solution in 0.9% NaCl and 0.9% benzyl alcohol.
Aprotinin is a protein consisting of 58 amino acids, arranged in a single polypeptide chain that is crosslinked by three disulfide bridges.
