Quorum Sensors

Quorum sensing is a chemical communication mechanism used by many common bacteria to initiate group behaviors implicated in bacterial pathogeneses and symbioses. Significant interest lies in the development of chemical strategies that interfere with quorum sensing-controlled behaviors. In collaboration with Professor Helen Blackwell, Sigma-Aldrich is proud to offer a suite of versatile and potent ligands that target LuxR-type receptors in Gram-negative bacteria. These are promising tools for modulating quorum sensing phenotypes in wild-type bacteria.
