TCO-PEG4-tris-PEG3-DBCO is a unique branched PEG linker comprised of a terminal TCO for fast, efficient click reactions with tetrazine-bearing biomolecules and three terminal DBCO groups for copper-free click chemistry with azide-bearing biomolecules. The PEG arms elevate the water-solubility of the compound.
