FAST-1 EMSA (Electrophoretic-Mobility Shift Assay) kit is used for monitoring FAST-1 DNA binding activities and activation. FAST-1 is a transcription factor involved in many cellular processes. Upon activation, FAST-1 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.
