I use TAE for running DNA on agarose up to three times with no ill
effects, but I change my 0.22M formaldehyde MOPS buffer for 
Northerns every time.  However, I do occasionally use yellowed
10X MOPS without problem.  This is probably a FAQ, but what 
exactly is the matter with yellowed MOPS anyway?
