Treated Induced Animal Liver Subcellular Fractions

Treatment of animals with various xenobiotics causes a marked induction of liver microsomal CYP levels, which, in chronic studies, may be associated with liver and/or thyroid tumor formation.  XenoTech provides subcellular fractions from dogs and rats treated with prototypical inducers to serve as positive controls for ex vivo enzyme induction studies.

These products are pooled from many animals to ensure good representation of the inducer and to provide sufficient product availability. The following lot-specific product information is included with each order of microsomes.

    •    Specific content of cytochrome P450
    •    Specific content of cytochrome b5
    •    NADPH-cytochrome c reductase activity
    •    Activity of the inducible CYP enzyme
    •    Dosing regimen
    •    Animal husbandry conditions
