Product Information

Description	N-(Amino-PEG4)-N-Fluorescein-PEG4-acid is a branched PEG linker containing a fluorescent dye, a primary amine, and a carboxylic acid group. Fluorescein is a near-UV/Vis spectrum dye. The primary amine is available for use as a nucleophile, while the carboxylic acid can be used as a scaffold for amide couplings or for forming heterocyclic compounds. The PEG linker provides aqueous solubility.
