MEF2 EMSA (Electrophoretic-Mobility Shift Assay) kit is used for monitoring MEF2 (Myocyte enhancer factor 2) DNA binding activities and activation. Upon activation, MEF2 can recognize and interact with the unique DNA binding sequence and form protein/DNA complex, which can be separated from free DNA due to the differences in their electrophoretic mobility in native (non-denaturing) polyacrylamide gels.
