M13 ssDNA stability

[Dubear Kroening]

Hello,

We are noticing degradation of M13 ssDNA when resuspended in water and 
heated at 90 degrees celcius for 10 minutes.  We see no degradation 
when just resuspended in water (without heating) or when resuspended 
in TE (with or without heating).  We were concerned that this may have 
something to do with magnesium in the prep.  Does anyone have any 
ideas at all?  Any comments or suggestions would be greatly 
appreciated.
