Abstract:Coimmobilization of L-lactate oxidase (LOD) and L-lactate dehydrogenase (LDH) on a film bound to an oxygen electrode makes it possible, by recycling L-lactate and pyruvate, to lower their detection limit to 10 nM. With LOD immobilized alone and LDH in solution, easy LDH measurements were performed. The detection limit was 1 IUl-1. Similarly, this mixed biosensor, using an LDH sensitive to mercurials, was used for p-chloromercuribenzoate (PCMB) detection. Coimmobilization of LOD + LDH with an NAD(+)-dependent d…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
