Product Information
Description: 8-Arm PEG-Vinylsulfone is a versatile PEG reagent featuring eight thiol-reactive vinylsulfone groups. VS reacts selectively with free thiols (SH groups) to enable site-specific PEGylation of peptides and proteins. Due to its eight-arm star structure and high functional group density, 8-Arm PEG-VS enables rapid and stable conjugation as well as multi-ligand co-modification (e.g. targeting ligands + drugs), making it suitable for drug delivery and high-strength hydrogels.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
