Title
Z-series Lattice-SIM images of bio-psoralen and RNA polymerase I in nucleus
Description
Z-series Lattice-SIM images of RNA polymerase I, DAPI and bio-psoralen in nucleus. The underwound DNA was labeled with biotinylated psoralen, which preferentially binds to underwound DNA rather than relaxed DNA, before cell fixation.

Biosample
Description
MC3T3-E1 mouse osteoblast-like cells in which underwound nuclear DNA was fluorescently labeled with psoralen
Extrinsic Variable
The biotinylated psoralen was applied to the cell and crosslinked to DNA by UV irradiation. After cell fixation, NeutrAvidin Protein, DyLight^{TM} 488 was applied and other staining was conducted.
