The major goal of the High-Throughput Technology Development Studio (TDS) is to provide expertise in assay development towards high-throughput applications and high content screening services (HCS). To this end the HT-TDS has state-of-the-art technologies for cell-based screening such as robotic liquid handling stations, plate readers and several automated microscopes. The services include developing complex automated image analysis pipelines and multi-parametric analysis of high content imaging applications.

Expertise

Assay and technology development for high-content screening in 2D and 3D cellular models (lab automation, siRNA & CRISPR transfection, chemical screening, automated microscopy, live cell imaging, image analysis, data management, multi-parametric statistics), robotic liquid handling processes (rearraying of libraries, hit picking, normalisation)

Interests

  • Application of automated image-based screening at subcellular resolution
  • Analysis of kinetic parameters of biological processes in medium-throughput mode with live cell automated microscopy
  • Identification of new gene functions and phenotypes after depletion or knock-down
  • Identification of new chemical or biological entities that induce equivalent phenotypes
  • Using chemico-genomic approaches to discover mode of action of compounds (comparison RNAi / KO and chemical screens)

  • Automated confocal microscopy
  • Automated widefield microscopy
  • Fluorescence emission
  • Fluorescence polarisation
  • HTRF (homogeneous time resolved fluorescence)
