SUNBRIGHT® PTE-050GS

SUNBRIGHT PTE-050GS is a 4-arm PEG derivative with a total molecular weight of 5,000 Da (approximately 1,250 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 PTE-050GS suitable for hydrogel formation and other biomedical applications requiring precise network construction.
