mTurquoise2 in Action (IMAGE) European Synchrotron Radiation Facility Caption This is an image of the actin filaments in a living cell that was taken using a fluorescence microscope. These filaments are major drivers for example of muscle contraction, and the fluorescing filaments can make this vital process visible in a living cell. Here, mTurquoise2 proteins were fused to a small protein that attaches itself to the actin filaments, allowing these to be visualized.
