Put on Your Para-spectacles: The Development of Optimized CRISPR-Cas13-Based Approaches to Image RNA Dynamics in Real Time (Molecular Cell)

Live-cell RNA imaging is a powerful approach to observe the real-time dynamics of RNA metabolism. Two recent papers describe an optimized fluorescence-based CRISPR-Cas13 approach to image colocalized or repeat-containing RNAs in real time, as well as demonstrate simultaneous RNA-DNA labeling by using Cas13 and Cas9 in tandem.
