Ainult teadustööks. Ei tohi kasutada diagnostilistes protseduurides.

PB/β-Naphtoflavone (phenobarbital/β-naphtoflavone)-induced Hamster Liver S9 fraction, liquid format. 5 mL bulk format. Post-mitochondrial supernatant pooled from Golden Syrian Hamster livers for extended or high-volume genotoxicity testing programs.

Hamster liver S9 is used preferentially in the Enhanced Ames Test (OECD 471) for nitrosamines, and in ADME pharmacokinetic studies. The distinct cytochrome P450 enzyme profile of hamster S9 enables detection of compounds preferentially bioactivated via hamster-specific metabolic pathways — complementing standard rat S9 for comprehensive species-specific mutagenicity screening.

• For Ames MPF, Ames II, umuC, and micronucleus genotoxicity assays
• Complementary CYP450 profile to rat S9
• Preferred for nitrosamines per OECD 471
• Liquid format — no reconstitution. 5 mL bulk format.
