Sekisui XenoTech has just established a method for high Aldehyde Oxidase and Xanthine Oxidase activity in pooled Human liver test systems.
These new test systems (Pooled Human Liver S9 and cytosol) have been prepared from tissue treated to preserve high Aldehyde Oxidase (AO) and Xanthine Oxidase (XO) activity, yet without significantly impacting major cytochrome P450 (CYP) activity.
