The Department's buildings are currently open for wet laboratory work only. We have carried out a comprehensive COVID-19 risk assessment process and have introduced a number of new measures to ensure the safety of our staff, including reduced building occupancy, strict social distancing, 'family'-based working, and increased cleaning and hygiene regimes. All staff who can work remotely will do so for the foreseeable future. Please continue to contact us by email until further notice.

Cryo-electron microscopy.

 

As the Cryo-Electron Microscopy Facility manager, my main area of interest is the use of cryo-transmission electron microscopy (cryo-TEM) in single particle analysis (SPA) and tomography.

In our Facility we provide access to electron microscopes, microscopy training, support and scientific guidance for academic and industrial users wishing to perform cryo-TEM experiments; beginning from cryo-TEM grids preparation through to particle reconstruction and refinement.
