Electron Tomography at ut houston
Our laboratory is interested in 3-D structure/function of molecular machines in cells. We develope two model systems (Lyme disease spirochete and E. coli minicell) to study the molecular basis of bacterial motility, signal transduction, and bacteriophage infection. In particular, a high-throughput cryo-electron tomography (cryo-ET) system has been developed to visualize the key molecular machines that orchestrate those processes at nanometer level.
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. We develop a high-throughput cryo-ET pipeline, which provides unparalleled opportunities for visualizing the molecular machines in cells.
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 (UCSF TOMO, IMOD, RAPTOR and Protomo) implemented, our system is able to achieve higher throughput and resolution.
