Research Focus

The focus of our research involves enabling technologies for High Throughput Screening (HTS) of any target of unmet therapeutic need. Our facility supports scientist and faculty locally as well as those in the US and throughout the world. We do this by implementing their biological applications into high density plates for HTS. The breadth of biology we deal with is virtually unlimited due to the diversity of skill sets of the scientist and engineers within our group as well as the expanded capability of the readers associated to our system. We operate a fully automated 1536 well compatible platform and perform HTS on large compound libraries such as the Scripps Drug Discovery Library (645K) or small focused collections (FDA approved drugs). We have expertise in microfluidics, low nanoliter volume liquid handling, ultra-sensitive plate reader technologies and informatics set-up to handle large volume data sets. Key components are high-content readers, imaging detectors such as the ViewLux and FLIPR Tetra, as well as pintool and acoustic transfer devices. Through collaborative efforts we have successfully translated multiple small molecules into the clinics. We are open to any pharmacology desired (agonist, PAMs, NAMs, inverse agonist, etc.) vs. kinases, GPCR, NHRs, proteases, phenotypic assays, etc. which can be applied to any therapeutic area; i.e. CNS, infectious diseases, cardiovascular, oncology, metabolic diseases. In addition, we are currently funded (R33CA206949) to develop 3D spheroid based uHTS assays for the purpose of testing molecules in a more phenotypically relevant format to cancer biology.
