Dynamics of glucose uptake by single Escherichia coli cells.

Abstract excerpt

The fluorescent glucose analog, 2-(N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino)-2-deoxyglucose (2-NBDG), was used to measure rates of glucose uptake by single Escherichia coli cells. When cell populations were exposed to the glucose analog, 2-NBDG was actively transported and accumulated in single cells to a steady-state level that depended upon its extracellular concentration, the glucose transport capacity of...
