For effective support and data documentation you need to fill in the requested information and send us the project application form
You may visit the Screening Unit, where we can help you in assay transfer to the 384well format and test your assay set up together for HTS usage. You will then be able to update the project application form with the revised protocol. Afterwards the materials for your next visit and primary screen plus validation are calculated.
We perform the primary screen together with one person from your team, the data are documented and analyzed automatically. You receive the raw data, statistic analysis, and statistics-based hit lists containing also structural data.
If desired, you may revise the hit lists. You send us a list of 352 compounds via e-mail.
We provide you with a 384-well plate containing your requested 352 hits, (4 µl 5mM compound in DMSO).
A small aliquot (0.2 µl) of your hit picking plate is taken and diluted in ACN/H2O for the LC-MS analysis. We analyze the samples in ACN/H2O (1:1, 25 µM) with our Agilent TOF mass spectrometer and determine the purity via UV absorption at 254 nm.
IC50 validation (using nine serial dilutions of the compounds in duplicate) is carried out by us, the data are analyzed automatically. You receive for a maximum of 352 "hit" compounds IC50 reports containing MS analysis data, frequent hitter information, data from biophysical and cytotox profiling. To our experience less then 10% of the compounds from the hit list of 352 can be expected to be true hits.
Our chemists revise with you the list of validated compounds and suggest proposals, which compounds might be selected for further characterization and optimization of leads.
Please bear in mind that all steps need only to be performed once per project!
The Screening Unit can assist your project with know-how gained from about 170 previous screens. But the data documentation, analysis and follow up studies are in the responsibility of the PI of the project.
The facility offers scientists from the FMP and MDC access to high-throughput screening with arrayed siRNA libraries on the basis of a scientific collaboration.
Broad range of assays
State of the art equipment supports a broad range of assays in high-throughput formats, ranging from basic reporter assays to high-content screening campaigns. Instrumentation covers automated fluorescence microscopy, luminescence and real-time kinetic fluorescence reading.
Full support in high-throughput screening
We operate on the basis of a scientific collaboration and offer support through all stages of a screening campaign: assay development and adaption to high-throughput screening, the actual wet-lab screen, data acquisition and quality assessment, statistical analysis as well as hit candidate selection.
Data processing
We are constantly advancing our in-house analysis, database and reporting tools to keep the platform updated. The integration of freely available open-source tools (e.g. KNIME Analytics Platform) and the development of our own analysis workflows enables us to meet the specific requirements of a multitude of biological questions.
The Surface Plasmon Resonance detection system allows automated screening for compounds (even 100 Dalton sized) which bind to proteins immobilized on chips. Different types of chip surfaces allow to couple proteins under mild conditions via His- or GSH- tags, by antibodies or strepravidine.
Specific biological activity of proteins must be controlled by defined binders and non-binders to monitor stability of proteins after repeated regeneration steps for removal of nonspecifically binding compounds.
Kd, plus On and Off rates can be calculated from kinetic data.
The service can be used to characterize small molecules that emerged as hit compounds from a screening project, but also user-provided compounds can be tested.
