Rat Liver S9 fraction (lyophilized), PB/BN-induced. 2 mL. For metabolic activation in Ames MPF, Ames II, and genotoxicity assays. Research use only.

Lyophilized rat liver S9 prepared from phenobarbital/β-naphthoflavone (PB/BN) co-induced rats. PB/BN induction is the standard method for generating rat liver S9 with broad cytochrome P450 metabolic activation capacity (CYP1A, CYP2B induction). This 2 mL format provides larger S9 supply for multi-assay programs or studies requiring repeated S9 preparations.

• PB/BN-induced rat liver S9 — broad CYP450 metabolic activation profile
• Lyophilized — stable long-term storage, consistent activity on reconstitution
• 2 mL format for multi-assay programs
• For use with Ames MPF, Ames II, and umuC genotoxicity assays
