pH and FISH

Dear All,

Does anyone know if the pH of a DNA probe interferes with its hybridisation?
 I ethanol ppt my probes before resuspending in the Hyb Buffer.  As this
involves 3M NaOac at pH 5.2, I wondered if residual salt left by inadequate
70% ethanol washes could upset the subsequent hybs?

I would appreciate any thoughts or comments.

Regards,

Ian
