Intensive temporal and spatial measurements were made of the isotopic label
in a wide range of organisms during the [N.
The choice of isotopic labels
for APIs varies, but typically includes carbon-14, tritium, deuterium, carbon-13 or nitrogen-15.
By using stable (as opposed to radioactive) isotopic labels
, these experiments can also be safely conducted in situ.
Stable Isotope Labeling Experiments (SILE) such as ICAT(TM), the more recently introduced ICPL(TM) technology, or even user-defined isotopic labels
are fully supported in the new software releases.
