6-Carboxyfluorescein (6-FAM) (CAS: 3301-79-9) is used as fluorescent labeling dyes, fluorescent labelling reagent. Used for nucleic acid sequencing and labeling.
6-Carboxyfluorescein is derivative of fluorescein giving stable derivative upon conjugation with biopolymers.
6-Carboxyfluorescein contains a carboxylic acid that can be used to react with primary amines via carbodiimide activation of the carboxylic acid. Fluorescein is the most common fluorescent derivatization reagent for labeling biomolecules. In addition to its relatively high absorptivity, excellent fluorescence quantum yield, and good water solubility, fluorescein has an excitation maximum that closely matches the 488 nm spectral line of the argon-ion laser.
6-Carboxyfluorescein is a useful reagent for the preparation of hydrolytically stable fluorescent conjugates and is a useful starting material for the synthesis of other fluorescein-derived reagents. Dyes and metabolites.
6-Carboxyfluorescein diacetate is a membrane permeable compound. It can be hydrolysed by intracellular esterases to form a membrane impermeable bright green fluorescent molecule.
