Subject area	Biology
More specific subject area	Super-resolution microscopy of cell nuclei.
Type of data	Tables, Figures
How data was acquired	Super-resolution localization microscopy data based on blinking of Vybrant® DyeCycle™ Violet dye with an affinity to nuclear DNA; 2D data constitute an optical slice (<500 nm thickness) through cell nuclei.
Data format	Analyzed SMLM list of positions and reconstructions.
Experimental factors	VERO-B4, HL-1or MSU 1.1 cell nuclei stained with the dye at a variety of concentrations and chemical environments.
Experimental features	Blinking of the green-emitting form of the dye induced by 491 nm laser of high intensity.
Data source location	Mainz, Germany; Krakow, Poland
Data accessibility	The data are with this article.
