The laboratory of Scott Lokey uses a small molecule approach, called chemical genetics, to study signaling pathways related to cell cycle checkpoints and the actin cytoskeleton. In one study, Lokey and his co-workers are developing screens of natural compounds that can be used to examine how cells detect their own DNA damage. Studies such as these might lead to development of a new class of chemotherapeutic agents.
HALO384: a halo-based potency prediction algorithm for high-throughput detection of antimicrobial agents.
Published in Journal of Biomolecular Screening
A high-throughput (HT) agar-based halo assay is described, which allows for rapid screening of chemical libraries for bioactivity in microorganisms such as yeast and bacteria. A pattern recognition algorithm was developed to identify halo-like shapes in plate reader optical density (OD) measurements. The authors find that the total growth inhibitio...
