Nikon SoRa Spinning Disk Microscope

Overview:

The Nikon Super Resolution Spinning Disk Confocal (SoRa) is a fully-loaded live cell imaging platform with dual disks (SoRa 50 μm) for super resolution and standard confocal imaging, Hamamatsu Quest 2 qCMOS & Andor iXon 888 EMCCD and, full incubation. The system is capable of up to 120nm resolution with the SoRa disk and 10s of nm with SMLM.  DNA-paint and some dyes are possible for SMLM, but please speak to the imaging team prior to your experiment.
