摘要:
There is provided a method by which multiple types of substances desired to be transferred into cells can be continuously transferred into multiple types of cells by a convenient procedure, a cell in which the substance desired to be transferred into cells has been taken up by this method, and an apparatus for transferring a substance into cells by this method. The foregoing objects can be achieved by electrospraying cells with a liquid free from the substance to be transferred into cells while the cells are kept in contact with the substance to be transferred into cells, or first electrospraying cells with a liquid free from the substance to be transferred into cells and then bringing the cells into contact with the substance to be transferred into cells.

摘要:
The present invention provides a method whereby a drug can be conveniently injected into the living body, without sticking a needle, from a device that is not in contact with the living body, and a device therefor. Specifically provided is a method for injecting a peptide drug such as insulin, and a device therefor. No special consumables are needed except the drug solution or suspension. The method and device comprise injecting a drug into the living body by electrospraying a solution or suspension of the drug from a nozzle to which high voltage is applied and which is not in contact with the living body.

An object of the present invention is to provide a salt of pyrroloquinoline quinone having a high solubility in water and in an organic solvent and a method for producing the same.According to the present invention, there are provided an ammonium salt of pyrroloquinoline quinone having a high solubility in water and in an organic solvent, consisting of a pyrroloquinoline quinone ion and an ammonium salt having a hydroxyl group.
摘要:
An object of the present invention is to provide a gel containing pyrroloquinoline quinone that is capable of easily forming a gel near room temperature and is useful even in the food sector, and a method for producing the gel. According to the present invention, there is provided a gel containing pyrroloquinoline quinone that uses pyrroloquinoline quinone itself as a gelling agent and a method for producing the gel by adding a salt of pyrroloquinoline quinone to water and subsequently adjusting the temperature or the pH to reduce solubility.
摘要:
The present invention provides a method for transferring a gene into cells, which is practically useful and can achieve high transfer efficiency, and also a composition for use in the method. By bringing a mixture of a composition comprising a diallylamine sulfur dioxide copolymer having a repeating unit represented by the formula (1) or a salt thereof and a gene into contact with a cell, a gene such as DNA and RNA can be transferred into a target cell safely and conveniently, and into a cell at a specific site with high gene transfer efficiency.

The present invention provides a method whereby, in transferring a gene into a cell by contacting the cell with a gene to be transferred into the cell in a container and then electrospraying a spray liquid free from the gene on the cell and gene in the container, the gene can be rapidly and conveniently transferred into the cell with high transfer efficiency while minimizing the degradation of the gene, and an apparatus therefor. A nozzle for electrospraying comprising a tube portion for applying a high voltage, which is made of an electrically conductive substance and located on the side of the spray liquid suction port, and another tube portion for spraying, which is made of an insulating substance and located on the side of the spray liquid ejection port. By using this nozzle, electrospraying can be performed while preventing a discharge phenomenon that causes degradation of the gene. Thus, transfer efficiency of the gene into the cell can be remarkably improved, and the gene can be rapidly and conveniently transferred into the cell.
