Fluorescein (FAM) is a bright fluorophore that has found an extremely wide application in life science research. The fluorophore is hydrophilic and its derivatives possess good solubility in aqueous buffers.

Fluorescein is compatible with a wide variety of fluorescent instrumentation - most instruments are equipped with FAM channel filters.

This product contains the pure 6-isomer of fluorescein.

Intracellular pH probe. Fluorescent label for amines and alcohols.

ChEBI: 6-carboxyfluorescein succinimidyl ester is an N-hydroxysuccinimide ester derived from 6-carboxyfluorescein. A fluorescent cell staining dye, it is cell permeable and covalently couples, via its succinimidyl group, to intracellular molecules, notably to intracellular lysine residues. It has a role as a fluorochrome. It is functionally related to a fluorescein (lactone form).
