With the variety of fluorescent proteins and multicolored probes that have been developed, it is now possible to label virtually any molecule. The ability to visualize protein dynamics in vesicles, organelles, cells, and tissues has provided new insights into how cells function in healthy and disease states. These insights include the spatiotemporal dynamics of processes like mitosis, embryonic development, and cytoskeleton changes. When studying live cells, common obstacles include phototoxicity and photodamage. To capture fast biological processes, it is crucial to keep the cells healthy and obtain crisp images for reliable data that are free of artifacts. Live‐cell microscopy often requires a compromise between image quality and cell health. During imaging, certain environmental conditions must be maintained to avoid changes in the cells. 

A variety of high-performance Leica live cell imaging solutions can overcome these challenges for live-cell imaging enabling new information for cellular physiology and dynamics to be discovered. 

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 ensure successful live cell imaging.

About Live Cell Imaging

Besides the structural organization of cells or organs, dynamic processes are a major contributor to a functioning biological entity. Naturally, these processes can be best observed in living cells with non-invasive techniques like optical methods, collectively called “live-cell imaging” methods. Live-cell imaging covers all techniques where live cells are observed with microscopes – from the observation of embryogenesis with stereo microscopes, via cell growth studies with compound microscopes, until studies of physiological states of cells or cellular transport using fluorescent dyes or proteins. Although being highly demanding for both, experimenter and equipment (e.g. imaging systems, climate control), live-cell imaging techniques deliver results that are indispensable for present-day research.

Your Live Cell Imaging Needs

To perform successful live-cell imaging experiments, using the right platform is critical. When choosing an optical microscope for live‐cell imaging, the following 3 variables should be considered: detector sensitivity (signal‐to‐noise ratio), specimen viability, and image-acquisition speed.

Methods suitable for live-cell applications enable visualization of the dynamics without causing cell damage, as it can affect the results.
