“…TR activity was measured by monitoring DTNB reduction at 405 nm (ε ¼ 13.8 mM À1 cm À1 at 405 nm) by means of a coupled assay that guaranteed the oxidation of T(SH) 2 [41]. All enzyme assays were performed at 30 C, in a final volume of 50 ml, and using a Multiskan Ascent one channel vertical light-path filter photometer (Thermo Electron Co.).…”

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.
