Biotin-PEG4-tris-PEG3-azide functions as a biotinylated, branched PEG linker possessing three azide groups to react with alkyne-containing biomolecules and a biotin moiety to react with amine entities in the presence of activators such as EDC or HATU. The PEG4 chain improves the compound's hydrophilicity. Branched linkers allow for more payload attachment to ADC. Reagent grade, for research use only.
