4-arm PEGs

  • 4-Arm PEGs is a family of multi-arm polyethylene glycol with hydroxyl groups at each terminal of the four arms. Pentaerythritol core is used in 4arm PEG raw materials and derivatives. The indicated molecular weight of the multi-arm PEG is the sum of the molecular weights of all the arms.
  • Applications may include bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization.
