Hotel Description

With the plethora of molecular information coming from genetic and proteomic studies, the demand for functional analysis of the identified gene products is overwhelming. The validity of microscopy-based methods for functional studies is that single cells and even single organelles can be analyzed, which yields unique and indispensable information for understanding molecular function within the context of the cell. Protein location is an important parameter for protein function and structure is unequivocally linked to function. When microscopy-based research is combined with genetic, proteomic, molecular and biochemical approaches, a full physiological ‘picture’ of cell life will ultimately be in reach. The Cell Microscopy Center harbors a combination of state-of-the-art microscopy techniques.

Expertise and Track Record

43500984157 Advanced CLEM imaging of antibodies targeting low expressing, clinically relevant cancer targets for the development of Antibody Drug Conjugates with J. Klumperman (UMC Utrecht)

The Cell Microscopy core is part of the Cell Biology group at the UMC Utrecht. We have provided the past decades services to local (Utrecht), national (Netherlands) and international research groups both public institutions and industry. Depending on the underlying scientific question the support ranges from routine electron microscopical techniques to advanced correlative light and electron microscopy (CLEM) techniques.


The CMC organizes on a yearly basis the following courses:

·         Basic course for resin embedding and sectioning

·         Basic course immuno- gold electron microscopy (Tokuyasu technique)

·         Advanced course for Correlative light and electron microscopy in which both life cell CLEM and Section Clem are covered.



·         Immuno electron-microscopical localisation and quantification of antimicrobial cathelicidins.

·         Sterelogical measurements of intracellular changes in BAR-T cells  after drug administration.

·         Description of bile canaliculus lumen changes in ATB8B1 mutated mice.
