EPR in Life Science
EPR is a significant tool in the field of life sciences, providing insight into the structure, function and reaction mechanisms of enzymes, membrane proteins, RNA/DNA. It can also be used to characterize/screen DNP agents. Moreover, using spin-labeled biomacromolecules, users can study their structure and dynamics. EPR detects and quantifies reactive oxygen and nitrogen species (ROS/RNS), including nitric oxide.
