Live-cell imaging of RNA transport in axons of cultured primary neurons

The use of fluorescent proteins has revolutionized the study of protein localization and transport. However, the visualization of other molecules and specifically RNA during live-cell imaging remains challenging. In this chapter, we provide guidance to the available methods, their advantages and drawbacks as well as provide a detailed protocol for the detection of RNA transport using the MS2/PP7-split-Venus system for background-free RNA imaging
