Quantitative Cluster Analysis Applications for N-STORM
Nikon’s N-STORM super-resolution microscope is applied to mapping the distribution of nucleosomes on chromatin fibers, shining a light on the mechanisms of chromatin folding, gene expression, and pluripotency. Multicolor STORM is used to explore how nucleosome distribution differs between differentiated and pluripotent stem cells and correlates with the distribution of other important factors in replication, such as RNA Polymerase II.

N-STORM with DNA-PAINT for Reliable Multicolor & 3D Single Molecule Localization Imaging
DNA-PAINT is a technique for single molecule localization microscopy. The sample is immunolabeled with specialized secondary antibodies conjugated to short DNA oligomers known as docking strands. Complimentary oligomers conjugated to fluorophore, known as imaging strands, are introduced in the imaging buffer and will transiently bind to docking strands – allowing single molecules to be localized. Herein multicolor and 3D DNA-PAINT is demonstrated on the Nikon N-STORM 4.0 system.
N-SIM and N-SIM E Super-Resolution
Nikon’s N-SIM and N-SIM E super-resolution systems double the resolution of conventional optical microscopes by combining “Structured Illumination Microscopy” technology with renowned Nikon objective lenses.
