Mal-PEG4-bis-PEG3-TCO is a branched PEG linker composed of a maleimide moiety for cysteine conjugation and two TCO moieties for rapid and efficient tetrazine conjugation. The PEG spacers bolster the hydrophilicity of the molecule. Branched linkers allow for more payload attachment to ADC. Reagent grade, for research purpose.
