About us

The IMTM High-Throughput Screening (HTS) core facility is one of the largest and a state-of-the-art screening robotic platform in academia. Our goal is to accelerate discovery and development of new potential small molecule therapeutics as well as to identify and characterize novel therapeutic/biological targets. We have over 10 years of experience in running large-scaled screening campaigns on a fully automated and flexible robotic platform (HighResBiosolutions Ltd.) Our qualified and skilled team has expertise in a liquid handling, robotic automation, variety of readout technologies and big data analytics and is ready to assist and collaborate with you to accomplish your project requirements.

 

Our skills: 

  • Screening assays in 384 – or 1536 – well plate format
  • Biochemical assays (e.g. protein – protein and protein – nucleic acid interactions, enzyme inhibition assays, receptor – ligand binding assays)
  • Cell - based  assays (e.g. cell proliferation assays, reporter gene assays for mapping the most significant signaling pathways and receptors)
  • Cell types: immortalized cell lines (non cancer and cancer), primary cells, stem cells, senescent cells, 3D cell cultures) 
  • Various detection methods (e.g. absorbance, luminescence, fluorescence, fluorescence polarization)
  • High content analysis (e.g. phenotypic assays, cell painting, cell cycle analysis, DNA damage/repair activity, cytoskeleton integrity, colocalization studies)
  • Compound Libraries:
    IMTM: Commercial compound library (over 3.000 compounds with known activity)
    IMTM: Proprietary Library (over 15.000 unique small molecules)
    IMTM: DrugLike Library (a collection of 100.000 small molecules with druglike properties)

 

HTS Screening Workflow 

 

Assay Development

The goal is to translate your benchtop test to reliable, robust, and reproducible assay suitable for HTS platform. This essential step allows to reduce the reagent costs and increase the throughput. We focus on miniaturization (transfer of the assay from tubes or 96 – well plate format to 384 – or 1536 – well plate format), optimization (concentrations of components, reagents stability, DMSO tolerance, incubation time, positive and negative controls,…) automation, and validation of your assay. 

Primary Screening

Routinely primary screening campaigns are single point assays. Only one defined concentration of the compound/molecule (10 µM) is evaluated against tested target in three interplate replicates. Based on the defined threshold the active molecules are selected.

Secondary Screening

In secondary screening (dose-response curve testing) the compound is tested over a range of concentrations (7 points, dilution factor 4) to determine the concentration that results in half maximal response (IC50 or EC50 value respectively). 

Hit Identification

Data from primary and/or secondary screens are stored and analyzed in different systems (e.g. Dotmatics software, Columbus Image Data Storage and Analysis System). Main task for our team is to select true hits, the most promising candidates. To successfully select the hit we do further assays such as orthogonal, counter – screening, selectivity and cytotoxicity assays.
