An Electrophoretic Mobility Shift Assay (EMSA), also known as a gel shift assay, is a technique used to study protein-DNA or protein-RNA interactions. The primary purpose of EMSA is to assess the binding affinity of a protein to a specific nucleic acid sequence, which can provide insights into the regulation of gene expression and other biological processes.
