electrophoretic mobility supershift assay

^ http://purl.obolibrary.org/obo/MI_0412

The EMSA supershift is a EMSA experiment carried out using a third lane loaded with the radiolabeled nucleic acid, a protein mixture and an antibody for a specific protein. If an extra retardation is observed, this is due to the formation of a larger complex including the antibody. By this approach, at least one protein of the complex is directly identified.
