I had been on the lookout for superior-high-quality liver microsomes for my investigate on hepatic enzyme induction and phenobarbital's outcomes on enzyme activity. The products from Creative BioLabs fulfilled my expectations. The liver microsomes from Phenobarbital-addressed Cynomolgus monkeys provided strong and reproducible benefits. They helped us elucidate the metabolic profile of various new drug candidates.
