Institut de Duve
Avenue Hippocrate, 75 - B1.75.05
1200 Bruxelles
The PICT core facility, managed by Dr Patrick Van Der Smissen, trains and provides the scientific community with fluorescence, confocal, multiphoton and super-resolution microscopy, as well as a wide range of sophisticated methods of vital confocal microscopy, immunolabeling and dynamics. It is also a source of collaborations and advices, providing users with the necessary expertise at all stages of the experiment, from sample preparation to analysis and interpretation of data. PICT also comprises Digital Histology Services, a facility offering full range services to analyse tissue sections, including sample processing, immunostaining with single or multiple visible or fluorescent dyes, acquisition of digital high-resolution images of entire tissue sections and computerized image analysis.
The core facility is supervised by Prof. Donatienne Tyteca and is run by Dr. Patrick Van Der Smissen for fluorescence microscopy services and Dr. Nicolas van Baren for digital histology services.
