SUNBRIGHT PTE-200TS is a 4-arm PEG derivative with a total molecular weight of 20 kDa (approximately 5 kDa per PEG arm), featuring NHS ester groups at each arm terminus. The multi-arm structure and NHS carbonate groups enable efficient crosslinking with amine-containing molecules, making PTE-200TS suitable for hydrogel formation and other biomedical applications requiring precise network construction.
