Fluorescent probes for intracellular RNA trackingThe Need: Intracellular RNA fluorescence labeling is a crucial technique for studying cellular processes and understanding gene expression. However, the conventional MS2 labeling method using protein fusion labels can have drawbacks, such as increased mass, potential steric accessibility issues, and interference with native RNA biology. There is a need for an alternative method that can efficiently and minimally perturbatively label RNA of interest without the use of cumbersome protein fusion labels. The Technology: Our technology, FLURIL tagging, introduces a novel approach to intracellular RNA and DNA tracking. It utilizes genetically encoded, uridine-rich internal loops (URILs) in RNA, consisting of four contiguous UU pairs, which can be specifically targeted with 1 kD bifacial peptide nucleic acids (bPNAs). This triplex hybridization approach allows for precise and effective labeling of RNA without significant structural perturbation. Commercial Applications:
