i often questioned this when i was in grad. school. i firmly believe it was somewhat of a superstition. i have fixed and not-fixed gels and then dried down and developed and i really never detected a difference. I think it really is based on the training of your PI -who in turns passes it down to us!<p>in theory though, i believe it is meant to make the bands appear more concise and not so diffused.
