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