Propidium 23-39 tumor necrosis factor Rattus norvegicus 96-105 10385649-9 1999 Using propidium iodide and fluorescence microscopy, we found that both TNF-alpha and Kupffer cell activation were necessary to drive hepatocytes toward lethal injury. Propidium 6-22 tumor necrosis factor Rattus norvegicus 71-80
