SUNBRIGHT® PTE-400NP

SUNBRIGHT PTE-400NP is a 4-arm PEG derivative with a total molecular weight of 40 kDa (approximately 10 kDa per PEG arm), featuring p-nitrophenyl carbonate groups at each arm terminus. The multi-arm structure and p-nitrophenyl carbonate groups enable efficient crosslinking with amine-containing molecules, making PTE-400NP suitable for hydrogel formation and other biomedical applications requiring precise network construction.
