About

Chemistry Platform

The chemical biology platform enables the use of chemical probes to understand biologic pathways and phenotype cellular states in health and disease. These probes may be directed at validated disease targets, or applied in a "forward genetic" approach that is systematic and less dependent on a priori assumptions. Platform activities encompass three interrelated efforts: 1) Synthetic chemistry, including the creation of novel small molecules, diversity oriented synthesis (DOS) and other libraries; 2) High-throughput screening and analysis, utilizing a variety of biochemical, metabolic, and high-content imaging measurements and 3) a Chemistry Core for the production and quality control of imaging probes that are not commercially available.
