| 摘要 |
The present invention provides a reagent for introducing a protein or gene into a cell. The reagent of the present invention is, for example, a reagent for introducing a protein or gene into a cell, which comprises a composition comprising a cationic amino acid type lipid represented by the following formula (I)-1:
(wherein in formula (I)-1: L is a single bond, -CONH-, or -S-S-; M 1 is -(CH 2 ) k - or -(CH 2 CH 2 O) k - (wherein k is an integer between 0 and 14); and m1 and m2 are each independently an integer between 11 and 21 (in this regard, when providing a reagent for introducing a gene into a cell, the case where both m1 and m2 are 15 is excluded)). |
