Zeiss Elyra PS.1 Super Resolution Microscope

Elyra is a super resolution microscope with Structured Illumination Microscopy (SIM), and Single Molecule Localization Microscopy (PALM or dSTORM for example).

Structured Illumination Microscopy (SIM) relies on light interfences creating moire fringes and improves the resolution by a factor of 2 (xy: 100nm; z: 250nm). Here are some recommendations for sample preparation for SIM.

Localization microscopy techniques such as dSTORM and PALM take advantage of the blinking properties of some fluorophores to calculate their precise location in a sample. The resolution is greatly improved (xy: 40nm ; z: 100nm via TIRF).
