8-arm PEG-SAA

Price range: $300.00 through $1,200.00

8-arm PEG-SAA is a multi-arm polyethylene glycol (PEG) derivative terminated with succinic acid amide (SAA) groups. The terminal carboxylic acid functionalities can be readily activated using carbodiimide coupling reagents such as EDC/NHS for efficient conjugation with primary amines. With eight reactive arms, 8-arm PEG-SAA is an excellent macromolecular building block for hydrogel synthesis, protein conjugation, tissue engineering, drug delivery, and biomaterials research.

Description

General Description

8-arm PEG-SAA is a branched PEG macromolecule functionalized with succinic acid amide (SAA) groups at the terminus of each PEG arm. The terminal carboxylic acid groups provide versatile conjugation sites that can be activated using EDC/NHS or other carbodiimide coupling chemistries to react with primary amines on proteins, peptides, antibodies, enzymes, polymers, and other biomolecules, forming stable amide bonds.

The eight-arm architecture provides a high density of functional groups, enabling efficient multivalent conjugation, hydrogel crosslinking, and the fabrication of three-dimensional PEG networks. Compared with linear PEG derivatives, 8-arm PEG-SAA offers enhanced crosslinking efficiency, improved mechanical strength, and greater flexibility in biomaterial design.

8-arm PEG-SAA is widely employed in hydrogel fabrication, protein immobilization, enzyme conjugation, tissue engineering, regenerative medicine, drug delivery, cell encapsulation, and surface functionalization.
