Aprotinin is a competitive serine protease inhibitor. Aprotinin reversibly binds to and blocks the enzymatic active site. Aprotinin inhibits a range of serine proteases including trypsin, chymotrypsin, kallikrein and plasmin.

Cell lines | mouse G8-1 and C2C12 skeletal muscle myoblasts |
Preparation method | Olating mouse G8- 1 myoblasts DMEM + 20% FBS (maintenance medium), in which they remain undifferentiated. When cells reache approximately 40-50% confluence, adding different protease inhibitors to the culture media and incubating cells overnight. Then switching cells to differentiation-promoting media (DMEM + 10% horse serum ?protease inhibitor) and incubating for 7 days. |

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
