8-arm PEG-Alkyne

Price range: $300.00 through $1,200.00

8-Arm PEG Alkyne is a multi-arm polyethylene glycol derivative containing eight terminal alkyne groups attached to a central core. The highly reactive alkyne functionalities enable efficient click chemistry with azide-containing molecules through copper-catalyzed azide-alkyne cycloaddition (CuAAC). 8-Arm PEG Alkyne is widely used in hydrogel synthesis, polymer crosslinking, nanoparticle functionalization, tissue engineering, and biomaterials research.

Description

General Description

8-Arm PEG Alkyne is a multifunctional PEG derivative designed for bioorthogonal conjugation and hydrogel fabrication. The eight-arm architecture provides a high density of terminal alkyne groups, allowing efficient conjugation with azide-functionalized polymers, peptides, proteins, antibodies, fluorophores, nanoparticles, and biomolecules via click chemistry.

The PEG backbone provides excellent water solubility, flexibility, biocompatibility, and minimizes nonspecific protein adsorption. The eight-arm configuration enables rapid network formation and high crosslinking density, making this polymer particularly useful for preparing hydrogels, injectable biomaterials, drug delivery systems, and three-dimensional cell culture matrices.

8-Arm PEG Alkyne is widely employed in click chemistry, regenerative medicine, tissue engineering, molecular imaging, polymer synthesis, and advanced biomaterials development.
