Site-directed spin labeling

Site-directed spin labeling is a chemistry technique used to study proteins, or molecules that are used by our bodies to create different functions. It is like using a light to follow what proteins do in our bodies. Scientists use this technique to look at how proteins work by tagging them with a chemical that has a magnetic part, called a spin label. When they shine a light on the proteins, the spin label reacts and creates a signal that the scientists can read and use to learn how proteins work. This helps them learn how proteins work, so they can find better ways to treat illnesses.
