GR/PR EMSA (Electrophoretic-Mobility Shift Assay) kit is used for monitoring GR/PR(Glucocorticoid receptor/Progesterone receptor) DNA binding activities and activation. GR/PR is a transcription factor involved in many cellular processes. Upon activation, it 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
