General description

8arm PEG Norbornene. Crosslinks into hydrogels. Norbornene NB PEGs are suitable for copper-free click chemistry reactions with tetrazines and for thiol-ene click reactions with thiols. 8ARM(TP)-PEG with tripentaerythritol core has a lower polydispersity and higher molecular weight accuracy compared with the generic 8ARM-PEG with a hexaglycerin core.


Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization
