SUNBRIGHT® HGEO-200GS

SUNBRIGHT HGEO-200GS is an 8-arm PEG derivative with a total molecular weight of 20 kDa (approximately 2,500 Da per PEG arm), featuring NHS ester groups at each arm terminus. Each NHS ester is linked to the PEG chain via a glutaric acid linker. The multi-arm structure and NHS ester groups enable efficient crosslinking with amine-containing molecules, making HGEO-200GS suitable for hydrogel formation and other biomedical applications requiring precise network construction.
