Fig. 1From: Improved DNase-seq protocol facilitates high resolution mapping of DNase I hypersensitive sites in roots in Arabidopsis thaliana Intact nuclei from Arabidopsis roots. Nuclei prepared using optimized protocol and Percoll density gradients were stained with DAPI and observed using fluorescence microscopy and UV-light (a) or confocal microscopy (b) according to standard proceduresBack to article page
