'''Nitrogen-15''' is a stable, non-radioactive ] of ]. It is often used in ] and ] research. Nitrogen-15 is frequently used in ] (NMR), because unlike the more abundant nitrogen-14, it has a ] ] of ½, which simplifies observation by NMR. ]s can be isotopical labelled by cultivating them in a medium containing only nitrogen-15. In addition, nitrogen-15 is used to label proteins in quantitative ] (e.g. ]). Nitrogen-15 is also more commonly found in the ocean, while Nitrogen-14 is more commonly found on land. This means that scientists can find out where the Nitrogen in soil and plants comes from. |
