An object of the present invention is to provide a carrier composition for nucleic acid delivery, which can efficiently deliver a nucleic acid into cells when a nucleic acid such as siRNA is administered to animal-derived cells or animals, and also has low toxicity and high safety, and a composition for nucleic acid delivery containing the carrier composition and nucleic acid.
A carrier for nucleic acid delivery is prepared by using (A) a diacylphosphatidylcholine, (B) at least one member selected from the group consisting of cholesterol and derivatives thereof, and (C) an aliphatic primary amine. Also, a composition for nucleic acid delivery is prepared by mixing the carrier for nucleic acid delivery with a nucleic acid.
本发明的目的是提供一种核酸递送载体组合物,当向动物源性细胞或动物递送 siRNA 等核酸时,该组合物能有效地将核酸递送到细胞中,而且毒性低、安全性高,还提供一种含有该载体组合物和核酸的核酸递送组合物。
一种用于递送核酸的载体是通过使用 (A) 二酰基磷脂酰胆碱、(B) 至少一种选自胆固醇及其衍生物组成的组的成员和 (C) 脂肪族伯胺来制备的。此外,还可通过将核酸载体与核酸混合制备核酸递送组合物。
