KLF4 EMSA (Electrophoretic-Mobility Shift Assay) kit is used for monitoring KLF4 (Kruppel-like factor 4) DNA binding activities and activation. Upon activation, KLF4 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.
