Flow cytometric analysis of the effects of tri-n-butyltin chloride on cytosolic free calcium and thiol levels in isolated rainbow trout hepatocytes

The toxic effects of tri-n-butyltin chloride (TBT) were investigated on isolated trout hepatocytes by flow cytometry (FCM). We developed a procedure permitting the study of cytosolic free calcium in these cells using the new fluorescent probe Fura Red. In parallel, changes in thiol levels upon exposure to TBT were also followed by FCM with the probe 5-chloromethylfluorescein-diacetate. Cell viability was monitored through FCM analysis using...
