SUNBRIGHT PTE-100PA is a 4-arm PEG derivative with a total molecular weight of 10 kDa (approximately 2,500 Da per PEG arm), featuring propylamine groups at each arm terminus. The amine groups react with various activated groups, such as NHS esters, carboxylates via coupling reagents, or aldehydes under reductive amination, enabling stable covalent bond formation. The multi-arm structure and reactivity of the amine groups make PTE-100PA suitable for hydrogel formation and other biomedical applications requiring precise network construction.
