Measuring ROS in Cells
Description
Reactive oxygen species, or ROS, are oxygen-derived molecules that can oxidize other molecules in cells. They are chemically active, and when ROS build up without control, they can damage DNA and other biological molecules. At the same time, ROS can also act in normal signaling inside the body.

Transcript
Reactive oxygen species produced in cells have been implicated in tissue homeostasis, cellular aging, and disease states like cancer. As their name implies, these molecules arise from oxygen, which naturally exists as a stable, dioxygen molecule since all its electrons are paired. The addition of one unpaired electron renders ...
