On Target Laboratories discovers and develops targeted intraoperative molecular imaging agents to illuminate cancer during surgery. Their molecular imaging technology, based on the pioneering work of Philip S. Low, PhD, Purdue University's Presidential Scholar for Drug Discovery and the Ralph C. Corley Distinguished Professor of Chemistry, is comprised of a near-infrared dye and a targeting molecule, or ligand, that binds to receptors overexpressed on cancer cells. The imaging agents illuminate the cancerous tissue, which may enable surgeons to detect more cancer that otherwise may have been left behind.
