WebAn electrophoretic mobility shift assay (EMSA, also known as a gel shift assay) is used to determine if a protein is able to directly interact with a short, specific sequence of DNA. Before the experiment begins, the investigator hybridizes two complementary DNA strands (about 30–40 bp in length) and labels the strands with a radioactive probe. WebGel shift assays, or EMSAs, are another technique used to study transcription factor binding. Here, the basic concept is that a piece of DNA will migrate through a gel more …

The Gel Shift Assay for the Analysis of DNA-Protein Interactions

An electrophoretic mobility shift assay (EMSA) or mobility shift electrophoresis, also referred as a gel shift assay, gel mobility shift assay, band shift assay, or gel retardation assay, is a common affinity electrophoresis technique used to study protein–DNA or protein–RNA interactions. This procedure can determine if a protein or mixture of proteins is capable of binding to a given DNA or RNA se… WebThe gel shift assay consists of three key steps: (1) binding reactions, (2) electrophoresis, (3) probe detection. The order of component addition for the binding reaction is often critical. Completed binding reactions are best electrophoresed immediately to preserve potentially labile complexes for detection.
