Seeing small-molecule interactions inside cells
(PHYSorg.com Chemistry)

Like people in a large company, proteins in cells constantly interact with each other to perform various jobs. To develop new disease therapies, researchers are trying to control these interactions with small-molecule drugs that cause specific proteins to associate more or less with their `coworkers.` Now, researchers reporting in ACS` journal Analytical Chemistry have developed a method to visualize whether drugs are regulating protein-protein interactions inside cells.
