    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.

    摘要: It is intended to provide a vector for delivering a target substance into a nucleus or a cell. This object is achieved by providing a vector for delivering a target substance into a nucleus or a cell which comprises a lipid membrane structure having a lipid membrane containing an anionic lipid such as phosphatidic acid, cardiolipin, etc.
