Studying Wound Healing of Smooth Muscle Cells

This article discusses how wound healing of cultured smooth muscle cells (SMCs) in multiwell plates can be reliably studied over time with less effort using a specially configured Leica inverted…

How to Prepare your Specimen for Immunofluorescence Microscopy

Immunofluorescence (IF) is a powerful method for visualizing intracellular processes, conditions and structures. IF preparations can be analyzed by various microscopy techniques (e.g. CLSM,…

Fluorescent Dyes

A basic principle in fluorescence microscopy is the highly specific visualization of cellular components with the help of a fluorescent agent. This can be a fluorescent protein – for example GFP –…

Download The Guide to Live Cell Imaging

In life science research, live cell imaging is an indispensable tool to visualize cells in a state as in vivo as possible. This E-book reviews a wide range of important considerations to take to…

Plant Cell Development and Morphogenesis

The article discusses how tubulin molecules, which make up microtubules, in plant cells can be studied with total internal reflection fluorescence (TIRF) microscopy to better understand tubulin…

Factors to Consider When Selecting a Research Microscope

An optical microscope is often one of the central devices in a life-science research lab. It can be used for various applications which shed light on many scientific questions. Thereby the…

Upright Fluorescence Microscopy for Virus Replication Studies

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019 and spread over the world quickly. Due to its dramatic impact, researchers are interested in the nature of the…
