Description Nanogen digs into DNA to diagnose disease. The company makes diagnostic reagents, instruments, and test kits that detect a variety of infectious diseases -- including several herpes viruses and influenza -- as well as some cancers and genetic conditions. Its Q-PCR Alert and MGB Alert tests employ real-time PCR technology (a method of DNA amplification commonly used in molecular testing) and its proprietary MGB technology. Nanogen also makes point-of-care tests, including a couple of tests administered in the emergency room to diagnose heart attack and congestive heart failure. Nanogen has filed bankruptcy and arranged to sell its assets to French diagnostics company Elitech for $25.7 million
