Visualization of RNA using fluorescence complementation triggered by aptamer-protein interactions (RFAP) in live bacterial cells.
This unit describes a method allowing RNA visualization in live cells. The method is based on fluorescent protein complementation regulated by RNA-aptamer/RNA-binding protein interactions. Based on these two principles, a fluorescent ribonucleoprotein complex is assembled inside the cell only in response to the presence of the aptamer sequence on the target RNA.
