VNIRTM FDA is a fluorescein-based membrane permeable, non-fluorescent precursor which upon hydrolysis turns to highly fluorescent fluorescein molecule in live cells. Dead cells cannot accumulate or hydrolyse FDA. Hence this probe can be used differentiate live cells from dead cells. This precursor is commonly used as a cell viability probe and also to measure cell-membrane integrity.
