THE UC BERKELEY EML

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:

  • Project consultation
  • Education and training for new users
  • Equipment for trained users who anticipate having long-term EM projects
  • Full service microscopy

All services are available to anyone with an interest in electron microscopy: graduate and undergraduate students, post-doctoral researchers, faculty, staff, and 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 ad hoc basis.  Use the Quotation form to request this service.  

In addition to providing training as a service, the EML supports two MCB courses: MCB 481 B and 481 C.  We encourage any UC Berkeley student working with a mentor on campus (undergrad or graduate level) to talk with us about taking the course. It is a great way to get trained to use the equipment in the facility.  See the MCB course section for more information.

EML STAFF

Danielle Jorgens is the director of the EML. She earned her PhD from UC Berkeley (2013) in Comparative Biochemistry, where she trained in advanced sample preparation techniques including cryopreservation for cells and tissues. She was a post-doctoral fellow and then a research assistant professor specializing in the ultrastructure of cancer biology at Oregon Health and Science University (OHSU). Her research interests focus on the ultrastructure of the nucleolus and nucleus in cancer and normal tissues. She is also interested in developing novel methods and applications for volume electron microscopy (Volume EM, FIB-SEM, SBF-SEM) and correlative light and electron microscopy (CLEM).

Misun Kang has expertise in various imaging and analysis techniques including light, electron microscopy, X-ray micro computed tomography, and X-ray fluorescence microscopy through graduate studies at UTK and postdoctoral training at UC Davis and UCSF. Misun has conducted extensive research on normal and pathological mineral formation in various tissues and organs such as teeth, bone, kidney stone, pulp stone, and peyronie’s plaque using correlative microscopy techniques. And now, as a new member of EML, Misun is eager to support researchers and students from a wide range of disciplines in their quest for new knowledge and discoveries. When not in the lab, Misun enjoys exploring the great outdoors by indulging in hiking and camping.

HOW TO CITE THE EML

The EML strives to provide excellent service to users and students and in-turn we hope that data collected in our facility enables excellent science.  For data collection or sample preparation conducted in our facility, by the user or our staff, we ask that the EML be acknowledged in the manuscript, publication or other media.  If a particular staff member assisted you, please acknowledge them specifically.  

An example of a general acknowledgement:

“Thank you to the staff at the University of California Berkeley Electron Microscope Laboratory for advice and assistance in electron microscopy sample preparation and data collection.”

Further, we would like to highlight and elevate the profile of our user’s work and as such request that any publications be shared with us electronically so that we can link to them from our website.  See our curated list of publications HERE.

We also appreciate that not all data makes it into a publication and we are always open to highlighting images collected by our users on our website.  If you have data that you wish to have highlighted in our GALLERY, please let our staff know!

Wishing Dr. Guangwei Min a Wonderful Retirement!

Our beloved Guangwei - truly a master of all things in the EML - is retiring from the EML after 15 amazing years.  He joined the EML in 2006, recruited from NYU out of his post-doc studying extracellular matrix proteins with cryoEM. We are going to miss his calm and reassuring nature here at the EML; along with his ability to fix everything from IT systems to changing fuses to repairing pumps. 

Guangwei, we wish for you a long and joyful retirement!  Thank you for all you've done for the EML, we will miss you!  Love, the EML Staff

If you'd like to send Guangwei a message, his min@berkeley.edu will be active during his retirement. 

Sept. 16 2021  The EML will need to close 9/24  All Day.  Independent users may still access the facility, please contact the staff to let us know your plans ucbeml@berkeley.edu.

Sept. 16 2021 The EML will need to close 9/20 1-5pm.  Independent users may still access the facility, please contact the staff to let us know your plans ucbeml@berkeley.edu

Jun. 21 2021 EML will be closed on Monday 06/28/2021 in observance of Juneteenth.

Feb. 25 2021 We will be shutting the facility for 2 weeks beginning March 15th and will reopen March 30.  

The entire floor of the facility will be re-done during this shutdown to fix an issue with the current flooring that was installed during the renovation.  Rooms 21 and 3 are affected, so there will be no access to the lab allowed during this time period

Jan 19. 2021 Any person coming to campus will require COVID testing in order to get access to any campus property - this includes one time access requests.  See this link to the UHS website.  This new requirement starts next week on 1/26.  Previously the only requirement was to fill out the symptom screener.

Oct 22.  Both TEM calendars are now available for scheduling. 

We separated our JEOL and Tecnai calendars, thus users may schedule time on either instrument as they wish. 

Oct. 22. Our Tecnai 12 is available again for scheduling!  Thank you all for your patience as the camera and filament issues were fixed.
