DBCO-PEG4-tris-PEG3-methyltetrazine is a multifunctional branched PEG linker featuring a DBCO group for azide-based copper-free click chemistry and three methyltetrazine moieties for fast, bioorthogonal reactions with trans-cyclooctene (TCO). The PEG spacers increase solubility and biocompatibility, while the branched design allows for higher payload loading in applications such as antibody-drug conjugates (ADCs). Reagent grade, for research use only.
