I'm going to start an experiment in which I look at hepatotoxicity of a medicine and I use HepG2 cells. I need to use an positive control. Anybody knows which one is reliable?
In addition to GGT (Ali's response), measuring alanine aminotransferase (ALT) is also a good indicator of hepatocellular damage. Acetaminophen is a good agent that can reliably induce hepatic injury.
