Electron Cryo-Microscopy Core Facility
Electron Cryo-Microscopy Core Facility
The mission of Electron Cryo-Microscopy (Cryo-EM) Core Facility at UTHealth is to provide researchers access to the state-of-the-art cryo-EM resources and expertise. Over the past decade cryo-EM has emerged as the most applied technique capable of determining structures of a wide variety of challenging biological structures ranging from individual molecules and their assemblies to subcellular organelles. To date, cryo-EM is a proven alternative to X-ray crystallography for 3-D structural analysis at atomic resolution. These remarkable advances open a new door in structural biology attracting a steadily growing community of researchers around the world motivated by the prospect of using cryo-EM to tackle high-resolution structures of molecular targets that are associated with human diseases but have not been amenable to the traditionally employed X-ray crystallography and NMR spectroscopy. UTHealth has created the Cryo-EM Core Facility to meet needs of researchers in the Texas Medical Center at Houston and nationwide who do not have adequate access to the latest cryo-EM instrumentation and expertise.
