NHS-PEG5-tris-PEG3-aldehyde is a branched PEG linker featuring three aldehyde groups for hydrazide/amine conjugation (hydrazone or imine bonds) and an NHS ester for efficient amine coupling. The PEG spacers boost water solubility, and the branched structure allows for increased payload attachment in ADC applications. Reagent grade, for research use only.
