Title Translation regulation system in cell or artifical cell model by using low-molecular-weight RNA
Abstract (EP2500427)
The present invention is related to a liposome comprising an mRNA or DNA and a cell-free translational system encapsulated therein.
Scope of claims [claim1]
1. A liposome comprising an mRNA or DNA and a cell-free translational system encapsulated therein.
[claim2]
2. A method for producing a liposome comprising an mRNA or DNA and a cell-free translational system encapsulated therein, comprising the steps of: mixing one or more phospholipids, the mRNA or DNA, the cell-free translational system, and an aqueous solution into an oily liquid to form a W/O emulsion in which the mRNA or DNA and the cell-free translational system are encapsulated in the phospholipid vesicle; adding an oily liquid containing outer membrane lipids dissolved therein, to an aqueous phase to form a molecular membrane in which the lipids are arranged at the oil/water interface; and adding the W/O emulsion to the oil phase side of the interface and moving the W/O emulsion to the aqueous phase side of the interface such that the outer membrane lipid is added outside of the W/O emulsion to form a liposome.
[claim3]
3. A method for real-time monitoring of intraliposomal protein translation reaction, comprising the step of microscopically observing the liposome after the liposome formation step according to claim 2.
