Gel Shift Assay Systems

The gel shift or electrophoretic mobility shift assay provides a simple and rapid method for detecting DNA-binding proteins. This method is widely used to study sequence-specific DNA-binding proteins such as transcription factors. The assay is based on the observation that complexes of protein and DNA migrate through a nondenaturing polyacrylamide gel more slowly than free DNA fragments or double-stranded oligonucleotides. The gel shift assay is performed by incubating a purified protein or a complex mixture of proteins (such as nuclear or cell extract preparations) with a 32P end-labeled DNA fragment containing ...
