Question

Quizplus · Accepted Answer

An electrophoretic-mobility shift assay is specifically designed to identify DNA sequences to which regulatory proteins bind. This assay involves running a gel electrophoresis on a sample containing the regulatory protein and the DNA of interest, and then observing changes in the mobility of the DNA bands on the gel as a result of the binding interaction. DNA affinity chromatography is a similar technique, but is more commonly used to isolate specific DNA-binding proteins from a complex mixture. Western blotting and Southern blotting are not used for identifying DNA regulatory sequences.
