A nucleic acid is effectively introduced into a cell while suppressing the cytotoxicity by administering a nucleic acid complex comprising a high molecular weight derivative of &#x3b5;-poly-L-lysine and a nucleic acid to a cell.

Nucleic acid complex and method of introducing nucleic acid into cell using the same

Disclosed is a gene carrier composed of a hydrogen-bonding polymer having a polymer chain with hydrogen-bonding sites formed on the polymer chain, in which the polymer chain has a conformation similar to the conformation of a nucleic acid, and particularly, the polymer chain has helix parameters similar to the helix parameters of a nucleic acid of a helix structure. In a preferred embodiment, the hydrogen-bonding polymer is composed of &#x3b2;-1,3-glucan such as schizophyllan. The carrier can be expected to be applied as a vector and a separator for nucleic acids because it is capable of interacting with a nucleic acid to form a complex with the nucleic acid and thus carrying the nucleic acid.

Gene carrier

Disclosed is a complex which comprises a carbon nanotube and a modified polysaccharide having a backbone chain with the side thereof being introduced with monosaccharide or oligosaccharide residues. The polysaccharide is preferably &#x3b2;-1,3-glucan. The complex is prepared by admixing a solution of the modified polysaccharide dissolved in an aprotic polar solvent or a strong alkali solution with an aqueous dispersion of the carbon nanotube, and incubating the mixture.

Polysaccharide-carbon nanotube complex

Disclosed is a new type of immunostimulating agent including an immunostimulating oligonucleotide complexed with a carrier which is safe and has a high transfection effect. The carrier complexed with the immunostimulating oligonucleotide to form the immunostimulating agent is a polysaccharide having &#x3b2;-1,3-bonds (preferably &#x3b2;-1,3-glucan such as schizophyllan). A preferred example of the immunostimulating oligonucleotide is one containing an unmethylated CpG motif. The polysaccharide for use is preferably modified with nucleic acid-binding functional group and/or cell membrane-affinitive functional group.

Immunostimulating agents

To provide a new technique by which efficient transfection is ensured in delivering a target gene into a cell, disclosed is a nucleic acid construct for nuclear import, which comprises a ternary complex consisting of a nucleic acid substance containing a gene to be delivered into the nucleus of a cell, an importin protein (for example, importin-&#x3b2;) capable of passing through the nuclear pore and involved in the nuclear transport, and a binding substance (for example, polyethyleneimine) bound to both of the nucleic acid substance and the importin protein. Nucleic acid transport from outside of a cell into the cell nucleus can be particularly promoted by administering the nucleic acid construct bound to a cell membrane receptor binding factor and/or a membrane fusing substance, or administering the nucleic acid construct encapsulated in a non-viral vector (for example, Sendai virus envelope) having cell membrane permeability and membrane fusing properties.

Nuclear transport nucleic acid delivery vector

Disclosed are gene carriers utilizing &#x3b2;-1,3-glucan and methods of preparing the same. The &#x3b2;-1,3-glucan has at least one 1,6-glucopyranoside branch and is chemically modified through periodate oxidation and reductive amination so as to impart nucleic acid-binding functional groups (for example, cationic functional groups) to at least some of the 1,6-glucopyranoside branches thereof. Triple helix &#x3b2;-1,3-glucan is dissolved in a polar organic solvent to form single-stranded &#x3b2;-1,3-glucan. By replacing, in the presence of a nucleic acid, the polar organic solvent for the solution containing the chemically modified single-stranded &#x3b2;-1,3-glucan by water, a complex (gene carrier) is formed in which the nucleic acid is bound to double-stranded &#x3b2;-1,3-glucan.

Gene carriers with the use of polysaccharide and process for producing the same

The present invention provides solid-phase saccharide dyes. The dyes are bisboronic acids covalently bonded to a solid substrate. The dyes selectively conjugate with saccharides, particularly glucose, and register a signal. The signal is proportional to the quantity of saccharide. Thus, the dyes of the present invention are useful for measuring and monitoring saccharide levels, particularly in biological fluids such as blood.

The compound emits fluorescence of a high intensity upon binding to saccharide(s), and is therefore suitable for use in the detection of saccharide(s).
