SUNBRIGHT PTE-400GS is a 4-arm PEG derivative with a total molecular weight of 40 kDa (approximately 10 kDa 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-400GS suitable for hydrogel formation and other biomedical applications requiring precise network construction.
