mPEG-SSG

mPEGn-SSG (succinimidyl succinyl glycolate) is designed for hydrolyzable PEGylation, enabling controlled release of conjugated therapeutics through ester bond cleavage in physiological environments. It is particularly useful for prodrug strategies and transient modification to reduce immunogenicity, though its hydrolysis kinetics are influenced by pH and local esterase activity, requiring application-specific optimization.
