Super-Resolution Microscopy Strategies in Cell Biology Using a Spinning Disk Microscope
Hosny N.A. et al. (2013) present a comparative study of super-resolution microscopy strategies using two methods of super-resolution microscopy; Photoactivation Light-Microscopy (PALM) and Stochastic Optical Reconstruction Microscopy (STORM), in conjunction with Spinning disk super-resolution imaging (SDSI) or Structured Illumination microscopy (SIM) and differing image analysis algorithms (RainSTORM, QuickPALM, GLRT, SOFI, 3B, Deconvolution-STORM (DeconSTORM), and Faster-STORM). Standard confocal microscopy has a resolution limit of 200nm, which has prevented further research into small molecular structures e.g. nuclear ultrastructure. Super-resolution microscopy has bypassed this resolution limit (described by Abbe's Law) and allowed for observation of structures as small as 30nm in size.
The study suggests that; 1) Multi-spectral SDSI can collect super-resolution images with good signal-to-noise (S/N), resolved in any selected axial plane within a cell. 2) PALM and STORM can both be used separately or in conjunction to produce super-resolution data. 3) SOFI has the best retention of image intensity information and provides the most accurate data reconstruction, in terms of spatially assigning all of the emission data found in the original images. 4) SIM was more appropriate for imaging 3D structures. 5) PALM/STORM SDSI could generate higher resolved data than SIM for single plane imaging dependent on the image processing algorithm used
