  • 製品の概要

    Extracellular Oxygen Consumption Reagent ab197242 is an oxygen-sensitive fluorescent dye; its fluorescence is quenched by oxygen. The dye is used in a mix-and-read, 96-well fluorescence plate reader assay for the real-time kinetic analysis of extracellular oxygen consumption rates (OCR). The oxygen consumption rate is a measure of the cellular respiration rate, and of mitochondrial function.


    The Extracellular Oxygen Consumption Reagent dye is used with an oil layer which is added on top of the assay medium to limit diffusion of oxygen into the assay medium. As mitochondrial respiration depletes the oxygen within the assay medium, quenching of the fluorescent dye is reduced, and the fluorescence signal increases proportionately.


    The dye and a suitable oil are available together in Extracellular Oxygen Consumption Assay Kit ab197243.


    The extracellular oxygen consumption assay that the dye is used in, is optimized for isolated mitochondria and cell cultures, and can be used with tissues, enzyme preparations, and small organisms.


    The dye excites at 360-380 nm (max 380) and emits at 630-680 nm (max 650).
