<p>It is intended to provide a drug- or gene-carrier composition having a lowered hemagglutinin activity. A drug- or gene-carrier composition having a lowered hemagglutinin activity (compared to the case without the addition) can be successfully constructed by adding a compound to an envelope protein having a hemagglutinin activity of a minus strand RNA virus. For example, a virus vector provided in an embodiment shows significantly lowered erythrocyte agglutination activity and hemolytic activity and thus the stability of the vector in blood is remarkably elevated. The drug- or gene-carrier composition thus provided can be adequately used in transferring a drug or a gene into a living body.</p> |
