The image was obtained using structured illumination microscopy (SIM, Deltavision OMX system) which provides 'super-resolution' beyond the diffraction limit set by the wavelength of the illuminating light.

After quenching in sodium borohydride, cells were immunostained for microtubules (primary antibody mouse DM1-alpha, secondary antibody donkey anti-mouse [-Xrat] Dylight 594, red), kinetochores (primary antibody rabbit anti-CenpE, secondary antibody donkey anti-rabbit-Alexa 488, green), and chromosomes counterstained blue with Hoechst dye. Images were captured and processed using a Deltavision OMX 3D-SIM Super-Resolution microscopy system in which structured illumination provides resolution that exceeds the diffraction limit. Through-focus Z-stacks of images were obtained with a 0.125 micrometer step size and a 100x 1.4 NA UNIPLANAPO objective lens, and the z-slices subsequently processed and projected down the z-axis."},"DATAQUALIFICATION":{"free_text":"PROCESSED;spatialmeasurements"},"TERMSANDCONDITIONS":{"free_text":"public_domain"},"IMAGINGMODE":[{"onto_name":"fluorescence microscopy","onto_id":"FBbi:00000246"},{"onto_name":"structured illumination microscopy (SIM)","onto_id":"FBbi:00000332"}],"DIMENSION":[{"Space":{"Image_size":1500,"axis":"X"}},{"Space":{"Image_size":1500,"axis":"Y"}}],"NCBIORGANISMALCLASSIFICATION":{"onto_name":"Hypsiprymnodon moschatus","onto_id":"NCBITaxon:65631"},"PREPARATION":{"onto_name":"glutaraldehyde fixed tissue","onto_id":"FBbi:00000011"},"VISUALIZATIONMETHODS":[{"onto_name":"Hoechst 33342","onto_id":"FBbi:00000052"},{"onto_name":"Alexa Fluor 488","onto_id":"FBbi:00000440"},{"free_text":"DyLight 594"}],"CELLTYPE":{"onto_name":"kidney epithelial cell","onto_id":"CL:0002518"}}},"Citation":{"Title":"Jane Stout, Indiana University, Claire Walczak, Indiana University (2013) CIL:44601, Hypsiprymnodon moschatus, kidney epithelial cell.
