Fluorescein-PEG12-(N-Boc)-Amine is a heterobiofunctional PEG linker containing a fluorescein dye and a Boc-protected amine group, which can be regenerated by mild acidic conditions and then be reactive with cabroxylic acid, activated NHS ester, carbonyl (ketone, aldehyde) etc. Fluorescein is a common fluorescent tracer (494nm/521nm) for staining cells, tissues, biomarkers or nanoparticles and this reagent can be used to tag biomolecules and nanoparticles.
