The EML staff will perform negative staining with uranyl acetate (or similar) or whole-mount grid prep and TEM imaging for your project.  Whole mount grid prep examples: intact bacteria, catalyst, powders, polymers, MOFs. 

The Tecnai 12 120kV TEM is an advanced transmission electron microscope that offers magnification ranges from 120X to 300,000X. The microscope has a lens designed to optimize imaging low contrast samples for biological or polymer material specimens.

 Images are collected with a state-of-the-art Gatan Rio16 CMOS 16MB camera.

Full Service Negative Stain Preparation and TEM Imaging

The Electron Microscope Laboratory (EML) is an imaging core and shared resource facility of the University of California at Berkeley.  Our mission is to provide high-quality electron microscopy services, education, and training for the UC Berkeley campus, other academic institutions, and private companies at-large.

The lab is equipped with high resolution transmission electron microscopes, scanning electron microscopes, high pressure freezer and full suite of ancillary sample preparation equipment to fit most EM-related needs. The equipment can provide nanometer scale analysis for biological, chemical and materials science.  

The EML offers multiple levels of service that correspond with the services and training each user desires:

All services are available to non-UC users.  

Please note, the EML now provides fee-for-service full service microscopy for campus and external users as our staff availability allows on an 

All external, non-UCB customers are required to comply with all UC visitor policies and lab rules.
