Preparation of Laser Microdissected Plant Cell and Tissue Material for Microchemical Analysis

Secondary plant metabolites are involved in various plant physiological and biochemical processes, allowing plants to interact successfully with their biotic and abiotic environment. Distribution…

Sample Preparation for GSDIM Localization Microscopy – Protocols and Tips

The widefield super-resolution technique GSDIM (Ground State Depletion followed by individual molecule return) is a localization microscopy technique that is capable of resolving details as small as…

Brief Introduction to Freeze Substitution

Freeze-substitution is a process of dehydration, performed at temperatures low enough to avoid the formation of ice crystals and to circumvent the damaging effects observed after ambient-temperature…

Acousto Optics in True Confocal Spectral Microscope Systems

Acousto-optical elements have successfully replaced planar filters in many positions. The white confocal, regarded as the fully spectrally tunable confocal microscope, was not possible without this…

Nobel Prize 2013 in Physiology or Medicine for Discoveries of the Machinery Regulating Vesicle Traffic

On October 7th 2013, The Nobel Assembly at Karolinska Institutet has decided to award The Nobel Prize in Physiology or Medicine 2012 jointly to James E. Rothman, Randy W. Schekman and Thomas C. Südhof…

Thermodynamic Considerations Regarding the LN2 in a High Pressure Freezer

Employing liquid nitrogen (LN2) as a coolant in the complex process of high pressure freezing raises certain considerations regarding phase transition not only of the liquid sample to be frozen but…

Brief Introduction to Contrasting for EM Sample Preparation

Since the contrast in the electron microscope depends primarily on the differences in the electron density of the organic molecules in the cell, the efficiency of a stain is determined by the atomic…

Brief Introduction to Glass Knifemaking for Electron and Light Microscope Applications

Glass knives are used in an ultramicrotome to cut ultrathin slices of samples for electron and light microscope applications. For resin and for cryo sections (Tokuyasu samples) the knife edge must be…

Brief Introduction to Coating Technology for Electron Microscopy

Coating of samples is required in the field of electron microscopy to enable or improve the imaging of samples. Creating a conductive layer of metal on the sample inhibits charging, reduces thermal…
