Notes on usage:

SIM imaging is extremely sensitive to spherical aberration. To get the highest quality images you need to minimize spherical aberration. This means:

  • You should mount only a single coverslip in the center of the slide.
  • You should mount in an appropriate mounting medium. Fixed samples should be mounted in high refractive index mounting media with antifade. Be aware that hard-set mounting medium can cause shrinkage when it cures. We also recommend that you do not use mounting medium which contains DAPI or other fluorophores.
  • You should have your sample as close to the coverslip as possible (e.g. cells grown on coverslip not on slide).
  • You should use bright and stable fluorophores.
  • You should select the correct immersion oil for you sample. You can use the GE immersion oil calculator to determine the best oil to start with. The also have the calculator as a phone app.

As a general rule, if the sample doesn't look good in widefield or confocal, SIM imaging will not improve it. You should make every attempt to optimize your staining and reduce background from out-of-focus fluorescence for the best results.
