SUNBRIGHT PTE2-200GS3 is a forked (2-arm) PEG derivative containing two precisely spaced NHS ester groups, with a total molecular weight of 20 kDa (10 kDa per PEG arm). These NHS ester groups readily react with amine-containing bioactive molecules to form stable amide bonds. Its unique forked structure facilitates controlled conjugate formation, making it particularly suitable for protein modification, PEGylation of biomolecules, and other applications requiring precise molecular spacing and orientation.
