Fluorescein is one of the most popular green fluorescent reagents used for in situ labeling of peptides, proteins and nucleotides. It reacts with primary amines via carbodiimide activation of the carboxylic acid. Fluorescein has relatively high absorptivity, excellent fluorescence quantum yield, good water solubility, and an excitation maximum that closely matches the 488 nm spectral line of the argon ion laser.
