Fluorescein toxicity
WebThe fluorescein ion diffuses out of damaged membranes; cells that do not fluoresce are considered nonviable. The limitation to this method is the assumption that membrane repair does not occur, and no damaged cell can recover. This method is useful for evaluating both membrane integrity and intracellular enzyme activity.
