High Throughput Microscopy Dutch Flagship Node

The Dutch High Throughput Microscopy flagship Node brings together the three leading screening centers in the Netherlands that have extensive experience with cell-based screening coupled to high content imaging and advanced microscopy. The integration of these three sites in one NL-HTM center creates a world leading expertise center in high-throughput microscopy for imaging based screening. Each center offers specific strength and expertise. Each of these sites has developed a high-end infrastructure covering a broad range of screening and imaging technologies. Leiden Cell Observatory is in particular experienced in high-throughput high-end microscopy using automated live cell time-lapse confocal microscopy in combination with focused RNAi and compound screening strategies. The CSC is specialized in automated high-throughput imaging based screens using low resolution high-throughput endpoint imaging. The NKI Screening Center is highly experienced and at the forefront in whole genome RNAi screening using genome-wide shRNA as well as siRNA libraries and the NKI Advanced Microscopy Center integrates high-end microscopy approaches into medium throughput automated microscopy settings.

Specialties and expertise of the Node

The Dutch HTM flagship Node is specialized in the development and application of cell based screening assays in 2D and 3D with image-based assays and readouts. Screening platforms compromise small molecule collections, functional genomic screening collections including CRISPR, shRNA and siRNA. Special interest and expertise lies in the use of advanced fluorescence based reporter cell lines to monitor live signaling dynamics. For automated image analysis, screen analysis and data integration we have developed relevant image analysis and bioinformatics pipelines using different open sources software for image quantification. Another area of expertise is the use of quantitative data for computational modelling to obtain a mechanistic understanding of observed phenotypes. We also have extensive experience in combining HCS with functional imaging assays, employing e.g. FRET sensors for readout of second messenger cascades, receptor activation and receptor internalization. New fast FLIM approaches have been implemented on our automated microscopes as well.
