ABSTRACT
Cryo-electron microscopy (cryo-EM) is used to characterize the structure of radiation-sensitive specimen, such as biological macromolecules. In cryo-EM, the sample is rapidly frozen in liquid ethane and kept at liquid nitrogen temperatures. It is then transferred to a cryo-microscope stage to be imaged while such low temperatures allow its structural preservation. By applying low-dose imaging protocols, efficient recording of high-resolution micrographs on advanced detectors is achieved and, finally, after image processing, high-resolution three-dimensional (3D) reconstructions are attainable. My laboratory is interested to derive 3D structures and interactions of biological macromolecules by cryo-EM and integrate EM data with biochemical, biophysical and biocomputational methods. In my talk, I will introduce cryo-EM and its importance in the structural research of biological macromolecules. Then, I will present cryo-EM applications on systems of interest, ranging from simpler polymer samples to complex biological macromolecules. I will conclude by highlighting the need to probe the structural organization of native cell extracts. Native cell extracts provide opportunities to uncover biomolecular states of metabolic complexes previously unknown.
