    Product Description

    Tris(4,7-diphenyl-1,10-phenanthroline)ruthenium II dichloride complex is a luminescent probe (absorption λmax: 455 nm, luminescence λmax: 613 nm) widely used for detection and quantitation of oxygen.1 The dye is strongly reduced by molecular oxygen as a result of dynamic quenching; thus oxygen detection can be based on either measurement of intensity or decay time.2 This oxygen probe has been used to optimize optical oxygen sensors, to measure oxygen flux through tissues and in skin tumors, and for oxygen imaging.1,3,4,5,6
