Abstract

The present invention provides a lipid particle which has low cytotoxicity, can stably hold a nucleic acid molecule outside a cell (in blood), and can escape from an endosome and rapidly release the nucleic acid in the cytoplasm; a nucleic acid transfer carrier; a compound for manufacturing a nucleic acid transfer carrier; a method for manufacturing a lipid particle; and a gene transfer method. The lipid particle contains, as constituents, a phospholipid having one or more amino groups and one or more nitrogen-containing heterocyclic groups, a neutral lipid not containing a nitrogen-containing heterocyclic group, a sterol, and a nucleic acid.
