Abstract
The present invention provides a gene-containing composition including a gene and a transporter, the transporter being capable of transporting the gene from a pregnant body to fetal cells. When this composition is administered to a pregnant body, birth of offsprings with gene deficiency can be prevented, and gene deficiency can be treated during pregnancy. In animal experiments, when an unknown gene is introduced to animals during their embryogenic stage, the function of the gene in ontogenesis can be elucidated. Moreover, the composition can be used for breeding animals such as pets, industrial animals and cattle.
Claims10
A gene-containing composition, which comprises:
- a) an operable gene;
- and
- b) a di-C10-C20-alkylamide glycylspermine;
- the di-C10-C20-alkylamide glycylspermine being present in an amount of about 1 to 100 nmol per μg of DNA.
A gene-containing composition, which comprises:
- a) an operable gene;
- and
- b) a di-C10-C20-alkylamide glycylspermine;
- wherein the operable gene is contained in a plasmid and the plasmid further contains a promoter and an enhancer, said promoter being organ-targeting.
A gene-containing composition, which comprises:
- a) an operable gene;
- and
- b) a di-C10-C20-alkylamide glycylspermine;
- the di-C10-C20-alkylamide glycylspermine and said operable gene being incorporated in micelles.
A gene-containing composition, which is obtained by mixing a solution containing an operable gene, and a di-C10-C20-alkylamide glycylspermine-containing solution and shaking the same, said di-C10-C20-alkylamide glycylspermine being present in an amount of from 1 to 100 nmol per μg of DNA.
A gene-containing composition, which is obtained by mixing a solution containing an operable gene, and a di-C10-C20-alkylamide glycylspermine-containing solution and shaking the same;
- wherein the operable gene is contained in a plasmid and the plasmid further contains a promoter and an enhancer, said promoter being organ-targeting.
A gene-containing composition, which is obtained by mixing a solution containing an operable gene, and a di-C10-C20-alkylamide glycylspermine-containing solution and shaking the same, said di-C10-C20-alkylamide glycylspermine and said operable gene being incorporated in micelles.
