| abstract |
The present invention provides a composition for nucleic acid introduction, which has low cytotoxicity and improves the transduction of the introduced nucleic acid and the expression in the cell. Formula (I) (In formula, R < 1> and R < 2> is the same or different, and is a C12-C22 saturated or unsaturated hydrocarbon group, R < 3> is a C1-C6 alkyl group or C1-C6 A hydroxyalkyl group, m means an integer of 1 to 10, X means a halogen atom.) A composition for introducing a nucleic acid into a cell containing a compound and a phospholipid. |
