Publication number: 20140179002Abstract: Plasmid vectors have been widely used as a carrier of a DNA sequence capable of expressing a target RNA in cells. However, construction of these plasmid vectors requires technical skill and time. Thus, a quicker and easier method is required therefor. To solve this problem, a method using a linear DNA that has been amplified by the PCR method is examined. However, this method is disadvantageous in that RNA expression in cells is extremely low. Under these circumstances, the present inventors attempted to develop an RNA expression method using a linear DNA which can be produced mainly by using the PCR method alone and which enables a high level of RNA expression. As the results of intensive studies on terminator sequences to be used in a linear DNA, the present inventors found a smallest unit of a terminator sequence enabling linear DNA expression equivalent to that when using a plasmid vector.Type: ApplicationFiled: April 27, 2012Publication date: June 26, 2014Applicant: YAMAGUCHI UNIVERSITYInventors: Rinji AKADA, Hisashi HOSHIDA, Mikiko NAKAMURA
