N-(C1-Mal)-N-bis(PEG2-NHS ester) is a branched PEG linker with two NHS ester groups for reacting directly and efficiently with amine-containing entities and a maleimide group for reacting with cysteine-containing entities. Water solubility is elevated via the PEG spacers. Branched linkers allow for more payload attachment to ADC. Reagent grade, for research purpose.
