Epoxy Resin Embedding of Animal and Human Tissues for Pathological Diagnosis and Research
Application Note for Leica EM AMW - The tissues were fixed in the modified Karnovsky fixative generally by immersion overnight (at minimum 4h at room temperature). Then pieces of approx. 1mm3 were cut…
Human Blood Cells Protocol

Critical point drying of human blood with subsequent platinum / palladium coating and SEM analysis.
Improvement of Metallic Thin Films for HR-SEM by Using DC Magnetron Sputter Coater
Preparation techniques, like several kinds of coating methods play an important role for high resolution scanning electron microscopy (HR-SEM). Nonconductive sample like biological and synthetic…
Workflows & Protocols: How to Use a Leica Laser Microdissection System and Qiagen Kits for Successful RNA Analysis
Laser Microdissection (LMD) allows isolating individual cells or chromosomes and is a well established technique for sample preparation prior downstream analysis of the nucleic acid content via PCR or…
Immersion Freezing for Cryo-Transmission Electron Microscopy: Applications
A well established usage case for cryo-TEM is three-dimensional reconstruction of isolated macromolecules, virus particles, or filaments. On one hand, these approaches are based on averaging of…
Immersion Freezing for Cryo-Transmission Electron Microscopy: Fundamentals
The high vacuum required in a transmission electron microscope (TEM) greatly impairs the ability to study specimens naturally occurring in an aqueous phase: exposing "wet" specimens to a pressure…
Video Tutorials: Filling and Assembling of Different Carriers for High-Pressure Freezing
High pressure freezing (HPF) is a cryo-fixation method primarily for biological samples, but also for a variety of non-biological materials. It is a technique that yields optimal preservation in many…
Brief Introduction to Specimen Trimming
Before ultrathin sectioning a sample with an ultramicrotome it has to be pre-prepared. For this pre-preparation, special attention must be paid to the sample size (size of the section), location of…
Glycerol Spraying/Platinum Low Angle Rotary Shadowing of DNA with the Leica EM ACE600 e-beam
Glycerol spraying/low angle rotary shadowing (Aebi and Baschong, 2006) is a preparation technique used in biology to visualize structures yielding insufficent contrast with other techniques, due to…
