Researchers Develop First Photo-controllable Fluorescent Protein for Epon Based Post-embedding Super-resolution Correlative Light-electron Microscopy[Oct 15, 2019]

A research team led by Dr. XU Tao and Dr. XU Pingyong from Institute of Biophysics developed the first photo-converted fluorescent protein mEosEM that remained fluorescence after routine EM preparation. The protein has photoswitchable property that are suitable for single molecule localization microscopy (PALM/STORM).
