Mal-PEG4-(PEG3-DBCO)-(PEG3-TCO) is a branched PEG linker with a cysteine-conjugating maleimide moiety, a DBCO for reacting with azides, and TCO for efficiently reacting with tetrazines. Water solubility is bolstered via the PEG spacers. Branched linkers allow for more payload attachment to ADC. Reagent grade, for research purpose.
Usually ships within 24 hours.
