Isopropanol & EDTA

[David MacHugh]

Hi,

Does anyone know whether very high concentrations of EDTA (~0.25M) will
affect DNA precipitations using isopropanol?  I have noticed that the
aqeuous material seems to separate out as a layer below the isopropanol. 
I haven't tried to recover the DNA yet, but I reckon it won't work.

Any comments..

Thanks in advance.
