SUNBRIGHT DX-200PA is an 8-arm PEG derivative with a total molecular weight of 20 kDa (approximately 2,500 Da per PEG arm), featuring propylamine groups at each arm terminus. The symmetrical structure, narrow polydispersity, and higher polymer purity ensure consistent performance in applications. 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. These properties make DX-200PA suitable for hydrogel formation and other biomedical applications requiring precise network construction.
