8arm PEG Vinylsulfone. Crosslinks into hydrogels. VS reacts with free thiol groups in aqueous buffer between pH 6.5~8.5 at room temperature. 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.
Synonyms: 8arm-PEG-Vinylsulfone, tripentaerythritol core; 8arm-PEG-VS
