    摘要: The invention provides a method of determining the amount of an analyte having an oxidation potential, for a one electron oxidation process, of about +0.10 to about +1.20 volts at pH 7, relative to the normal hydrogen electrode at 298K, said method comprising measuring the emission intensity or emission lifetime, at two or more wavelengths, from a sample comprising said analyte and two or more different macrocyclic lanthanide (III) complexes, wherein each of said macrocyclic lanthanide (III) complexes comprises a different lanthanide ion but the same macrocyclic ligand, and using a ratio of emission intensities or emission lifetimes measured at two different wavelengths to calculate the amount of analyte in said sample.

    摘要: Systems, including compositions, kits, and methods, particularly for photoluminescence applications. The systems may include, among others, (1) organic chelators, (2) complexes between the chelators and lanthanide ions, and (3) precursors, derivatives, and uses thereof. The chelators may include a 1,4,7,10-tetraazacyclododecane ring system, for example, having the formula: Here, R1, R2, and R3 are substituents of the tetraazacyclododecane ring system, that is further substituted at the 10-position by a sensitizer Z that is typically a polyheterocyclic ring system. The organic chelator may be capable of forming a luminescent complex with a lanthanide ion, and is optionally further substituted by a reactive functional group or a conjugated substance. The resulting lanthanide complex may be useful in luminescence-based assays, such as energy transfer assays, among others.
