Emsa-no binding band result s-emsappt 267 proteins capable of binding to specific sequences of nucleic acid are detected through the use of the electrophoretic mobility shift assay (emsa. Mobility shift assay protein bound to a small piece of dna will alter the electrophoretic mobility of that dna fragment this allows the analysis of protein-dna interactions, including the measurement of binding rates, affinity, and specificity.
Electrophoretic mobility-shift assay if there are multiple proteins that are bound to dna, there should be a visible supershift electrophoretic mobility diagram. The gel retardation assay, also known as the bandshift assay or electrophoretic mobility shift assay (emsa), is used to detect dna-binding proteins in crude cell extracts and to study the binding activity of purified dna-binding proteins it is also applicable to the study of rna-protein.
