The water soluble 5(6)-FAM PEG3 alkyne (protected) has a long PEG3 spacer that separates the dye carboxyfluorescein (commonly known as FAM) from the terminal acetylene group

including high photostability

Fluorescein is one of the most popular green fluorescent reagents used for in situ labeling of peptides, proteins and nucleotides. 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.
