Cellular electron microscopy has been a key technique for understanding the cell’s core elements and mechanisms since the 1950s. Electron microscopic methods have laid the foundation for a number of Nobel Prizes and have given us much of the basic understanding of human cells’ overall structure, physiology and mechanisms—basically the foundation of all modern medicine.
In recent years, electron microscopy has undergone extremely rapid development through a combination of significantly better optics, sample processing, detectors and image processing. The development has given rise to the so-called “Resolution Revolution,” which in recent years has gradually increased the average resolution of biological preparations significantly. Part of the discoveries and methodology resulted in a Nobel Prize to Richard Henderson, Jaques Dubochet and Joachim Frank. At the beginning of this revolution, a visionary decision of the then Karolinska Institutet’s (KI’s) leadership was made to build premises for a future electron microscopy center nearby the Biomedicum building at the KI Solna campus. These premises have now been built specifically for high-end biomedical electron microscopy. During 2019-2020 we will equip the newly built KI 3D-EM center with the best possible equipment and thereby enable a much broader group of KI researchers to utilize the enormous advances in electron microscopy in recent years.

Access and booking
Please contact facility manager Sergej Masich who will send a link to our temporary booking system. We will utilise the central KI core-facility booking system once that is available.
Teaching and training
We will arrange courses and workshops. In the beginning, teaching and hands-on-training on specimen preparation and microscope operation is provided to smaller groups or on a one-to-one training. Please contact Sergej.Masich@ki.se for a booking link.
Prices for service
Prices for service and access for equipment currently available:
- Training is free for KI personnel (main academic association KI). However, the microscope time is charged at normal rate.
- Talos 120C G2 cost 200 SEK per hour with minimal booking time of 3 hrs.
- Krios G3i with K3 cost 5000 SEK per 24h slot or 2000 SEK per 3h Autogrid screening slot.
- Consultant work or assistance outside training 550 SEK per hour.
- Usage of sample preparation equipment 100 SEK per hour with minimal booking time 2 hrs.
Note for other academic access/training: Pricing for access for other academic access/training is twice the prices stated above (except hourly staff time charge). Only KI personnel may be main operators of the instruments so staff setup time will typically need to be added to the total cost of access for external academic users. All prices are subject to local KI overhead (currently 22.5%). For industry access, please contact us."
