CLING (CRISPR-Display Live-Cell ImagiNG) is a method for visualizing chromatin dynamic in vivo (pictured on the right). CLING exploits the multiplex ability of CRISPR-Display to label endogenous genomic sites with unique fluorophores, allowing the behavior of these loci-their localization, mobility, interactions with other genomic sites and subnuclear structures, etc. — to by observed in real time.
