    摘要: The present invention aims to provide a cationic lipid that can be used as a nucleic acid delivery carrier, a lipid membrane structure using a cationic lipid, a nucleic acid-introducing agent using a cationic lipid, and a method of achieving nucleic acid introduction by using a nucleic acid-introducing agent containing a cationic lipid. A lipid membrane structure containing a cationic lipid represented by the formula (1)

    wherein each symbol is as defined in the DESCRIPTION, is superior in the stability in blood and tumor accumulation property. A nucleic acid-introducing agent using the cationic lipid can achieve high nucleic acid delivery efficiency of nucleic acid to be delivered into the cytoplasm.

    摘要: It is intended to provide a positively charged liposome, particularly having a polyarginine peptide on a surface thereof, which is capable of increasing the resistance to a negatively charged biological component such as a protein in the blood and maintaining a high ability to deliver a substance even in the blood. An agent for enhancing the resistance of liposome against biological component comprising a peptide having at least one of the following characteristics (a) and (b) as an active ingredient:
    (a) A peptide comprising an amino acid sequence represented by SEQ ID No: 1 or 2; and
    (b) A peptide comprising an amino acid sequence represented by SEQ ID No: 1 or 2, in which one or more amino acids are deleted, substituted or added, and having an activity for promoting lipid membrane fusion under acidic condition. An agent for enhancing the resistance of liposome against biological component in this invention, being included in a liposome, is capable of increasing the resistance to a negatively charged biological component such as a protein in the blood and maintaining a high ability to deliver a substance even in the blood.
