An improved resazurin-based cytotoxicity assay for hepatic cells.

An Improved Resazurin-Based Cytotoxicity Assay for Hepatic Cells

This study presents an improved resazurin-based cytotoxicity assay for screening cytotoxicity in hepatocytes and liver cell lines. The assay involves exposing human hepatoma (HepG2) cells to known toxic and control compounds and measuring fluorescence after adding resazurin. The improved assay consists of measuring fluorescence at two distinct time points, revealing two independent cytotoxicity endpoints with one vital dye. First, viable liver-derived cells slowly convert resorufin to nonfluorescent metabolites, leading to decreased fluorescence over time. Second, dead or dying cells convert resazurin to resorufin, but do not further metabolize it, resulting in the accumulation of resorufin and increased fluorescence over time.
