Product Description:
Fluorescein diacetate is widely used in biological and medical research as a vital stain to assess cell viability. It is particularly effective in fluorescence microscopy, where it helps differentiate between live and dead cells. When introduced into living cells, the non-fluorescent compound is hydrolyzed by intracellular esterases, producing fluorescein, which emits green fluorescence under UV light. This property makes it a valuable tool in cytotoxicity assays, cell proliferation studies, and environmental monitoring for microbial activity. Additionally, it is employed in ophthalmology for diagnostic purposes, such as evaluating corneal epithelial integrity and detecting eye injuries. Its application extends to flow cytometry, where it aids in analyzing cell populations based on their metabolic activity.
