Q one: How can phenobarbital-treated cynomolgus monkey liver microsomes Examine to human liver microsomes with regards to drug metabolism and enzyme activity? A: Phenobarbital-handled cynomolgus monkey liver microsomes are frequently used to be a model for learning drug metabolism due to their enzyme induction characteristics, which may mimic hepatic enzyme induction in humans.
