Video Tutorial: How to Change the Bulb of a Fluorescence Lamp Housing
When applying fluorescence microscopy in biological applications, a lamp housing with mercury burner is the most common light source. This video tutorial shows how to change the bulb of a traditional…
Fluorescence Correlation Spectroscopy (FCS)
Fluorescence correlation spectroscopy (FCS) measures fluctuations of fluorescence intensity in a sub-femtolitre volume to detect such parameters as the diffusion time, number of molecules or dark…
CARS Microscopy: Imaging Characteristic Vibrational Contrast of Molecules
Coherent anti-Stokes Raman scattering (CARS) microscopy is a technique that generates images based on the vibrational signatures of molecules. This imaging methods does not require labeling, yet…
Image Processing for Widefield Microscopy
Fluorescence microscopy is a modern and steadily evolving tool to bring light to current cell biological questions. With the help of fluorescent proteins or dyes it is possible to make discrete…
The Principles of White Light Laser Confocal Microscopy
The perfect light source for confocal microscopes in biomedical applications has sufficient intensity, tunable color and is pulsed for use in lifetime fluorescence. Furthermore, it should offer means…
Controlling the TIRF Penetration Depth is Mandatory for Reproducible Results
The main feature of total internal reflection fluorescence (TIRF) microscopy is the employment of an evanescent wave for the excitation of fluorophores instead of using direct light. A property of the…
Basic Principles of Luminescence
There are a lot of light-emitting processes occurring in nature. Luminescence is an umbrella term for those kinds of events where light emission is not the result of high temperatures. This article…
Introduction to Live-Cell Imaging
The understanding of complex and fast cellular dynamics is an important step to get insight into biological processes. Therefore, today’s life science research more and more demands studying…
Total Internal Reflection Fluorescence (TIRF) Microscopy
Total internal reflection fluorescence (TIRF) is a special technique in fluorescence microscopy developed by Daniel Axelrod at the University of Michigan, Ann Arbor in the early 1980s. TIRF microscopy…
