CRISPR/Cas9 For Photoactivated Localization Microscopy (PALM)
We demonstrate that endonuclease deficient Clustered Regularly Interspaced Short Palindromic Repeats CRISPR-associated Cas9 protein (dCas9) fused to the photo-convertible fluorescence protein monomeric mEos3.1 (dCas9-mEos3) can be used to resolve sub-diffraction limited features of repetitive gene elements, thus providing a new route to investigate high-order chromatin organization at these sites.
