Vibrational Spectroscopic Imaging in Cells, Tissues and Model Organisms

Here we present a webinar on the emerging applications of Stimulated Raman Scattering Microscopy, covering the following topics: Quantitative spectroscopic imaging of label-free or chemically tagged…

Development of Fluorescence Lifetime Imaging Microscopy (FLIM) and its Relevance for Functional Imaging

Prof. Ammasi Periasamy, Director, Keck Center for Cellular Imaging, University of Virginia, was interviewed by Dr. Giulia Ossato, Product Manager functional imaging, during Leica Microsystems Meets…

DIVE Multiphoton Microscope Image Gallery

Today’s life science research focusses on complex biological processes, such as the causes of cancer and other human diseases. A deep look into tissues and living specimens is vital to understanding…

Mammalian cell culure. Phase contrast and fluorescence image.

Introduction to Mammalian Cell Culture

Mammalian cell culture is one of the basic pillars of life sciences. Without the ability to grow cells in the lab, the fast progress in disciplines like cell biology, immunology, or cancer research…

About the Most Important Considerations When Imaging Deep Into Mouse Tissue

When operating a confocal microscope, or when discussing features and parameters of such a device, we inescapably mention the pinhole and its diameter. This short introductory document is meant to…

Gene Editing with CRISPR/Cas9 - Breakthrough in Genome Engineering

The CRISPR/Cas9 system is one of several different bacterial systems for defense against viral attacks. It consists of two main components. One is a small piece of RNA which binds to the viral target…

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…

Brief Introduction to Freeze Fracture and Etching

Freeze fracture describes the technique of breaking a frozen specimen to reveal internal structures. Freeze etching is the sublimation of surface ice under vacuum to reveal details of the fractured…
