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.
