摘要:
Nucleic acids comprising a nucleic acid moiety and two or more transfection enhancer elements (TEE's) according to the general formula (I): Hydrophobic moiety—pH-responsive hydrophilic moiety, wherein said pH sensitive hydrophilic moiety of said TEE is independently a weak acid having a pka of between 4 and 6.5 or is a zwitterionic structure comprising a combination of acidic groups with weak basis having a pKa of between 4.5 and 7.
