As I remember from ancient days of using M13 to sequence, the mobility of single stranded 
and double stranded DNAs differ in TAE and TBE.  The relative migrations are very dependent 
on agarose concentration.  Perhaps in one buffer system the single and double stranded DNAs 
comigrate and in the other system they are separatedScott Hodgson wrote:
