'''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 ], it has a ] ] of ½, which simplifies observation by NMR. ]s can be isotopically labelled by cultivating them in a medium containing only nitrogen-15. In addition, nitrogen-15 is used to label proteins in quantitative ] (e.g. ]). |
|

It is a product of ] ] in ]s. |
