The HTS Facility is a state-of-the-art technological hub that performs HTS of chemical and natural product libraries (we will likely be adding fragment based and miRNA libraries in the future).

We provide lab space, cell culture facilities and a full suite of detection, robotic and imaging equipment designed to facilitate work in microwell plates (96 or 384 well formats) to users engaged in drug and probe discovery efforts. The Facility also assists investigators in the design and development of screen assays that can use all currently available assay readouts and formats.

Services Provided

  • Consultation on the design of high throughput assays.
  • Biological/Biochemical assay optimization.
  • Development, testing and screening of libraries using cell-based high-content imaging, cell-based conventional or biochemical-based screens.
  • Cherry-picking of potential lead compounds and identification of lead candidates.
  • Development of secondary assays and counter-screens.

Capabilities and Instrumentation

  • Cell culture hoods, cell culture incubators, microfuges and centrifuges, liquid nitrogen cryopreservation, refrigerators and freezers.
  • Perkin Elmer Operetta high-content imaging system w/ environmental control chamber, rapid microscopic analyses of a wide variety of cell behaviors, wide-field and fluorescence illumination switchable to confocality and 2X, 10X, 20X and 40X objectives, 8 excitation filters and 6 emissions filter to enable the detection of fluorophores ranging from UV to far red. Robotically integrated with both a Liconic cell incubator and an ambient specialized storage device.
