The facility serves HHMI labs and their collaborators. We offer state-of-the-art instrumentation as well as staff with expertise in structural and cell biology, who provide services spanning the entire cryo-EM workflow.

High-quality, high-throughput data collection

Facility staff operate the microscope, optimize imaging conditions/parameters, and set up automated data collection while users focus on evaluating and selecting targets for data collection (remotely or in-person) on cryo-EM grids that are pre-prepared and provided by users.

CryoFIB milling

For cells frozen on a cryo-EM grid that are too thick to image on the Krios microscope directly, we offer an FEI Aquilos Cryo Focused Ion Beam (cryoFIB) system to mill regions of interest into a thin lamella. The cell lamella can then be loaded into the Krios microscope for imaging or tomography data collection.

To help locate regions of interest before cryoFIB milling, a Leica cryoCLEM light microscope is available to image the cryo-EM grid.

Additional services

Preparation of samples not prepared on a cryo-EM grid (e.g., protein complex solution or purified cellular components or cells), including:
- Calibrating and evaluating samples
- Plunge freezing
- Utilizing the Chameleon or cryoFIB milling systems, if needed
- Screening on cryo TEM
Large volume data collection
Image processing
3D reconstruction

Facility staff will interact closely with lab members during these processes. This type of work is research-oriented by nature and should be considered as a collaboration between the lab and the facility.
