Abstract: The number of peptides having an ability to bind to a cell or penetrate into a cell is narrowed down by being selectively enriched from a random peptide library with a diversity of not less than one hundred millions of peptides using a phage surface display technique, and then cytoplasmic transfer is evaluated by using protein synthesis inhibition as an indicator by adding to a cell, a fusion body of the selectively enriched peptide and a protein synthesis inhibitory factor (PSIF) that cannot solely penetrate into the cell.

Abstract: Disclosed is a physiologically active complex which comprises a proteinaceous part with TNF activity and a high molecular part bound artificially to the N-terminus of the proteinaceous part. The proteinaceous part in the complex has the amino acid sequence of SEQ ID NO:2 where Xaa is a member selected from the group consisting of asparagine, alanine, arginine, serine, threonine, proline, methionine, and leucine; while the high molecular part in the complex is a homopolymer of polyethylene glycol, copolymer of polyethylene glycol, or a derivative thereof.

Abstract: A substance of interest is contained in nanospheres which are then encapsulated in fusogenic liposomes to prepare transport carriers that allow physiologically active substances, especially those having high molecular weight such as proteins and genes, to be introduced into cells efficiently and which permit the introduced active substance to be released in the cell at controlled rate. The fusogenic liposomes are prepared by conferring the fusogenic capability of Sendai virus to known liposomes.
