SUMMARY
I n a new approach t o the specific labelling of organic compounds with tritium use is made of isotope exchange with tritium of certain specific hydrogen atoms in o q a n i c molecules when stirred u i t h tritiwn gas i n solution at room tewpemture i n the presence of a metal hydrogen t m n s f e r catalyst. Specifically labelled t r i t i a t e d compounds of high specific a c t i v i t y and mdio
SUMMARY
Acmunte knowledge o f the s t a b i l i t y of (3R)-uridine, (381-thyridineMisleading calculations of rates of uptake etc., may be caused by an invalid assumption of the initial purity of the radiotracer; this has lead to the incorrect suggestion of the presence of an isotope effect (5p6*).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
