Traditionally, researchers uniformly label proteins with 13 C and 15 N to enhance the NMR signals of these naturally low-abundance isotopes. In addition, exchanging protons for NMR-silent ...

Stable isotope-labeled amino acids are introduced to the system at a defined RIA. In this example, dietary RIA = 0.5. Dilution from other tissues will lower the true precursor RIA for protein ...

China claims that it has achieved success in starting mass production of a radioactive isotope –Carbon-14, which has wide ranging uses in science and medicine. The mass production of carbon-14 ...

From therapeutic ingredient production ... that uses the isotope lutetium-177, or 177Lu, in tandem with a prostate-specific membrane antigen, or PSMA. This is a targetable protein that prostate ...
