NHS-PEG5-tris-alkyne constitutes a branched PEG linker comprised of an NHS ester for efficient reactions with amine-containing biomolecules, and three alkyne moieties for reactions with azide-containing molecules. The PEG5 units improve the compound's water solubility and biocompatibility. Branched linkers allow for more payload attachment to ADC. Reagent grade, for research use only.
