Live Cell Imaging Fluorescence Microscopy

Frap is used to determine the mobility of fluorescently tagged proteins in live cells.

Live cell imaging fluorescence microscopy.

Fluorescent proteins are currently the probes of choice for live cell imaging. When coupled to recent technical advances in widefield fluorescence and confocal microscopy including ultrafast low light level digital cameras and multitracking laser control systems the green fluorescent protein and its color shifted genetic derivatives have demonstrated invaluable service in many thousands of live cell imaging experiments. Fluorescence recovery after photobleaching. Some of the more common systems used for imaging live cells are discussed below.

There are different types of microscopy compatible with live cell imaging which include both conventional contrast techniques like differential interference contrast dic or phase contrast and fluorescence based techniques. Recent advances in fluorescent dye development and imaging technology have resulted in the widespread adoption of using live cell imaging in many diverse areas such as developmental and stem cell biology medical research drug discovery and environmental studies. Fluorescence imaging of live cells is a powerful approach to the study of dynamic cellular processes and events. Live cell imaging is a microscopy technique that allows in vivo imaging of cells instantly and over a period of time.

The more widely used systems are discussed first and then the less commonly used systems are described. Live cell imaging was pioneered in first decade of the 20th century. Leica application suite x las x is the imaging and analysis software for live cell imaging from basic documentation to advanced fluorescence imaging including super resolution and confocal microscopy. Live cell imaging is the study of living cells using time lapse microscopy it is used by scientists to obtain a better understanding of biological function through the study of cellular dynamics.

Imaging systems for live cell microscopy the successful imaging of living cells and tissues relies on enhancement of contrast using advanced optical techniques such as phase and differential interference contrast dic hoffman modulation contrast hmc and fluorescence. Cali is a useful technique for selectively deactivating target molecules.
