Abstract: A multifunctional molecular complex for the transfer of a nucleic acid composition to a target cell is provided. The complex is comprised of A) said nucleic acid composition and B) a transfer moiety comprising 1) one or more cationic polyamines bound to said nucleic acid compositions, 2) one or more endosome membrane disrupting components attached to at least one nitrogen of the polyamine and 3) one or more receptor specific binding components.

Abstract: A container for liquids is configured for two-plane stacking with one or two similarly constructed containers; it comprises a body having a rectanguloid configuration with a top wall defining a recessed liquid pouring spout area and a raised handle area. The bottom wall has an underface included within a downwardly extending peripheral border defined by a series of spaced legs and pockets between the legs. The configurations of the top and bottom walls allow such containers to be stacked in two planes: one plane includes containers one directly above the other or one above the other but vertically offset thereto; a second plane includes containers in vertical planes 90.degree. to one anoother. The handle area has rectangular planar faces and a handle bar therebetween, both cooperating with the legs and pockets of one or two superposed containers to secure them in stacked relations.
