Structured Illumination Microscopy (SIM) Imaging Comparison with Confocal
The super-resolution microscopy technique structured illumination microscopy (SIM) imaging of dendritic spines along the dendrite has not been previously performed in fixed tissues, mainly due to deterioration of the stripe pattern of the excitation laser induced by light scattering and optical aberrations.
Reflectance imaging for visualization of unlabeled structures using Nikon A1 and N-SIM
Reflectance imaging allows the user to form an intensity image from light backscattered by the sample. Highly reflective markers, including a variety of nanoparticles, allows for imaging with very high signal-to-noise and virtually free of photobleaching, ideal for both confocal and structured illumination microscopies.
N-SIM for Quantitative Ultra-Structural Analyses of the Nuclear Lamina
Super-resolution Structured Illumination Microscopy (SIM), available from Nikon via the N-SIM and N-SIM E systems, allows for the observation of details inaccessible to traditional microscopes, such as confocal and widefield. In this application note we see how the N-SIM system enables quantitative multi-color evaluation of the distribution of different nuclear lamin proteins and the structures they form.
