The phosphoramidate linkage between ODN and PEG was completely cleaved within 5 hours in an endosomal acidic condition (pH 4.7)," scientists in South Korea reported.
"When complexed with a cationic fusogenic peptide, KALA, the ODN/PEG conjugate self-associated to form polyelectrolyte complex micelles in an aqueous solution. The anionic ODN segments were ionically interacted with...
