FEI Tecnai Twin 120kV transmission electron microscope (TEM)
This TEM provides several modes for directly imaging cell and macromolecular ultrastructure. The TEM can be used to examine negatively-stained specimens, cryo-specimens and sections of resin-embedded specimens. It is equipped with a Gatan Ultrascan 1000 2K CCD camera. A 70° tilt cryo-transfer holder enables frozen specimens to be imaged at temperatures below -170 °C. Software and hardware are available for acquiring and aligning tomography data for subsequent reconstruction and for single particle analysis.
