FLUOROGENIC NUCLEIC ACID MOLECULE AND TARGET-RNA FLUORESCENT LABELING METHOD

摘要

The present invention provides a fluorogenic RNA capable of visualizing mRNA in cells, particularly, living mammalian cells, and a target RNA fluorescent labeling method using the fluorogenic RNA. The present invention provides a fluorogenic nucleic acid molecule containing a base sequence having 2 or more fluorescent molecule-binding regions linked via a linker sequence, in which 1 or more fluorescent molecule-binding aptamer sequences are inserted into a scaffold sequence of each of the fluorescent molecule-binding regions.
