摘要
Methods to determine the activity of any and all DNA binding factors, proteins or fragments thereof based upon the detection of a change in a luminescence or fluorescence signal are provided. Preferably, a fluorescence donor is attached to a nucleic acid comprising one portion of a DNA binding element and a fluorescence acceptor is attached to a nucleic acid comprising the other portion of the same binding element. Alternatively, a microsphere bead is attached to a nucleic acid comprising one portion of a binding element and a luminescent moiety or fluorochrome is attached to a nucleic acid comprising the other portion of the same binding element. Binding of a DNA binding factor to the nucleic acid components affects a change in luminescence. These methods may also be used to detect mediating analytes, to diagnose diseases and/or screen for drugs that mediate the activity of DNA binding factors.
