Fluorescein-PEG3-Amine is a fluorescein dye with excitation/emission maximum 494/517 nm containing a free amine group, which can be reactive with carboxylic acid, activated NHS ester, carbonyl (ketone, aldehyde) etc. The hydrophilic PEG spacer increases solubility in aqueous media and reduces steric hindrance during binding.
