Cryo-ET Facility at UT Houston

We have a 300 kV Liquid Nitrogen cooled field-emission gun cryo-electron microscope (FEI Polara) and Tietz F415SP 4k x 4k CCD camera at UT Houston. This cutting-edge cryo-EM facility supports multiple NIH funded projects. In 2013, we got a Shared Instrumentation Grant from NIH and replaced our CCD camera with a new generation direct electron detector (Gatan K2 Summit). Together with advanced tomography packages (SerialEM, IMOD, TOMO3D and Protomo) implemented, our system is now able to achieve higher throughput and resolution.

We are very grateful that our research projects are supported by NIH, NIAID, NIGMS, and Welch Foundation.

High-throughput Cyro-electron tomography (cryo-et)

Cryo-Electron Tomography (cryo-ET) is one of the most exciting technologies to determine 3-D architecture of molecular machines in situ at molecular level. Our high-throughput cryo-ET pipeline provides unparalleled opportunities for visualizing the molecular machines in cells. 

Our laboratory is dedicated to developing a high-throughput cryo-electron tomography (cryo-ET) pipeline for high-resolution structure determination of molecular machines in cells. Our state-of-the-art imaging system has been utilized to gain molecular insights into fundamental biochemical processes: bacterial motility, chemotactic signaling, protein secretion, and DNA translocation.
