Cryo-Electron Microscopy (Cryo-EM): The “Ice Age” Revolution in Seeing Life’s Machinery

For decades, high-resolution protein structure determination relied heavily on techniques such as X-ray crystallography and NMR spectroscopy. While these methods remain powerful, crystallization requirements and sample-specific limitations can make some targets challenging to study. That limitation is now a relic of the past, thanks to Cryo-Electron Microscopy (Cryo-EM) . By rapidly vitrifying biomolecules in a thin layer…
