SUNBRIGHT PTE2-400EA is a forked (2-arm) PEG derivative containing two precisely spaced primary amine groups, with a total molecular weight of 40 kDa (20 kDa per PEG arm). These amine groups readily react with various activated functional groups (e.g., NHS esters, carboxylates via coupling reagents, or aldehydes under reductive amination) to form stable covalent linkages. 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.
