Abstract
DNA and RNA quantifications are essential in various fields such as biomedicine, agriculture, fishery, environment, and food. We have developed an accurate and cost-effective method for the quantification of specific nucleic acid sequences; the method involves the use of the fluorescent quenching phenomenon via an electron transfer between the dye and a guanine base at a particular position. This paper describes the elemental key technologies and their synthesis for the development of such a gene quantification method. Furthermore, based on the findings of a collaborative research project with a private company, we report the scenario for the industrialization and the practical use of the developed method.
