Bridging Structure and Dynamics at the Nanoscale through Optogenetics and Electrical Stimulation

Nanoscale ultrastructural information is typically obtained by means of static imaging of a fixed and processed specimen. However, this is only a snapshot of one moment within a dynamic system in…

Drosophila larvae - Sample Preparation for Cryo-SEM

Application Note for Leica EM ACE900 - Drosophila larvae were sandwiched between two 3 mm aluminum slit carriers with the 100 μm cavities facing each other and high-pressure frozen with a Leica EM…

Giardia lamblia - Sample Preparation for Cryo-SEM

Application Note for Leica EM ACE900 - A 100 mesh copper grid (12 um thickness) was dipped into a concentrated Giardia suspension and sandwiched between two flat 3 mm aluminum specimen carriers with…

High-Pressure Freezing and Freeze Substitution of Hep-2 Cells Infected with Chlamydia pneumoniae

Application Note for Leica EM HPM100 - Hep-2 cells infected with Chlamydia pneumoniae were cultured on carbon-coated 6 mm Sapphire discs. Cells were high-pressure frozen in an EM HPM100 using the 6 mm…

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…
