Watching Real-time Chemical Activity In CellsAttempts to identify potential drugs that interfere with the action of one particular enzyme associated with heart disease and similar health problems led researchers at Johns Hopkins to create a new tool and new experimental approach that allow them to see multiple, real-time chemical reactions in living cells. Their report on the work is published July 21 in the journal ACS Chemical Biology.
