Spectral Detection – How to Define the Spectral Bands that Collect Probe-specific Emission

To specifically collect emission from multiple probes, the light is first separated spatially and then passes through a device that defines a spectral band. Classically, this is a common glass-based…

Brief Introduction to High-Pressure Freezing

Water is the most abundant cellular constituent and therefore important for preserving cellular ultra-structure. Currently the only way to fix cellular constituents without introducing significant…

Step by Step Guide for FRAP Experiments

Fluorescence Recovery After Photobleaching (FRAP) has been considered the most widely applied method for observing translational diffusion processes of macromolecules. The resulting information can be…

Every Clue Counts – Forensics Inconceivable Without Microscopy

There is no crime without clues. They may be obvious, like a cartridge case at the scene of the crime or clear signs of crowbar damage on a door. But sometimes, clues are microscopically small.…

Perusing Alternatives for Automated Staining of TEM Thin Sections

Contrast in transmission electron microscopy (TEM) is mainly produced by electron scattering at the specimen: Structures that strongly scatter electrons are referred to as electron dense and appear as…

Widefield Calcium Imaging with Calcium Indicator Fura2

In eukaryotic cells Ca2+ is one of the most widespread second messengers used in signal transduction pathways. Intracellular levels of Ca2+ are usually kept low, as Ca2+ often forms insoluble…

Brief Introduction to Critical Point Drying

One of the uses of the Scanning Electron Microscope (SEM) is in the study of surface morphology in biological applications which requires the preservation of the surface details of a specimen. Samples…

QTM B, 1963, the first commercial automated image analysis system for microscope images, based on a TV camera and developed by Metals Research in Cambridge, England.

50 Years of Image Analysis

Modern image analysis systems perform highly sophisticated image processing functions on images from an automated microscope and digital camera. 50 years ago, the first image analysis system was…

Stem Cells in the Aging Process – the Signal Protein p53 as "Guardian of the Genome"

The physiological process of aging is an elementary part of life. The processes responsible for the aging process and the effect they have is one of the key focuses of biomedical research. Dr. Yvonne…
