摘要： According to an arrangement, a lipid composition is for delivering an objective substance (3) to a target cell. The composition is contacted with the target cell under an environment of 37°C or higher. The composition includes a substance delivery carrier having lipid particle (1) and an objective substance (3) encapsulated in the lipid particle (1). The lipid particle (1) constitutes a liposome and includes FFT-10 and/or FFT-20 as constituents thereof.
