Web11 nov. 2024 · To fully differentiate into hepatocyte-like cells and reach optimal expression of metabolism enzymes, HepaRG cells are conventionally cultured for 14 days in the presence of DMSO after an initial 14-day period of proliferation to achieve high-density confluence (Aninat et al. 2006; Cerec et al. 2007 ). WebWe’ve developed a cost-effective genetic toxicology screening program that uses non-GLP approaches — a computational assessment of QSAR for genotoxicity, a mini Ames test and micronucleus assay — which can be used prior to our GLP-compliant, validated genetic toxicology test battery.
