Methods of detecting a plurality of sequence specific DNA binding proteins with oligonucleotide detection duplexes

摘要

Compositions and methods are provided for detecting and measuring DNA-binding proteins. The compositions and methods permit the simultaneous or near-simultaneous detection of multiple DNA-binding proteins in a multiplex or array format, and can be used to generate profiles of DNA binding activity by proteins, specifically, transcription factors. Multiple protein-DNA binding events in a single sample may be detected and quantitated in a high-throughput format.
