A firefly luciferase assay for subnanomolar concentrations of amphipathic substances.


A sensitive assay is described for accurately quantitating subnanomolar aqueous concentrations of a wide variety of amphipathic and hydrophobic biological materials. This paper extends a luciferase-luciferin method previously used to measure aqueous concentrations of anesthetics to a variety of hormones, metabolites, and membrane active agents. The assay… (More)
