产品概述
lyophilized powder, 3-8 TIU/mg solid Molecular Weight : 6511.44 Molecular Formula : C284H432N84O79S7 Description This product is a lyophilized powder with activity of 3-8 TIU/mg of solid powder. Aprotinin is freely soluble in water (>10 mg/mL) and in aqueous buffers of low ionic strengths. Dilute solutions tend to be less stable than concentrated ones, though solution stability also depends on pH. Aprotinin is relatively stable against denaturation - only thermolysin has been found capable of degrading it at 60-80°C. Sterilizaiton of Aprotinin can be achieved through filtration by a 0.2 μm filter. Unit Definition One Trypsin Inhibitor Unit (TIU) will decrease the activity of two trypsin units by 50%, where one trypsin unit will hydrolyze 1.0 μmole of N-alpha-benzoyl-DL-arginine p-nitroanilide per minute at pH 7.8 and 25°C. Another commonly used unit is the KIU, with 1 TIU = 1,300 KIU. Storage condition 2-8°C For Research Use Only. Not For Use In Diagnostic Procedures.
