Novel organometallic reagents, such as the stable cobalt and molybdenum carbonyl complexes of hex-4-ynoic acid N-hydroxysuccinimide ester which are detectable at very low concentrations by Fourier transform infrared spectroscopy, couple with amine residues of peptides under mild conditions and provide a non-radio isotopic alternative for the widely used radioactive Bolton-Hunter tracer.
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.
