radiolabeling
Adding radioactive markers
Radiolabeling is the process of attaching a radioactive isotope to a molecule so it can be tracked through a biological system or chemical process.
Scientists use radiolabeled compounds to trace metabolic pathways, study drug distribution, or detect diseases: The researchers used radiolabeling to follow the protein's movement through cells.
Also spelled radiolabelling.
