Abstract

Objective: To investigate the effect of digestion enzymes on metabolic biotransformations in suspensions of isolated rat hepatocytes. Isolated rat hepatocytes are a valuable whole cell in vitro tool for drug metabolism and toxicity studies. Several modifications of the original two-stage collagenase perfusion technique (Seglen 1972) have been reported for the preparation of hepatocytes. However, there are very limited published data on the influence of isolation procedures on phase 1 and phase 2 biotransformations in rat hepatocytes.
