problems with RNAs denatured with Glyoxal(in Northerns)

[Saverio Brogna Genetics]

Please someone,

could you explaine why when I run Northerns with RNAs denetured in Glyoxal 
I see two bands from my transcript, and anly one when I used the more 
commun formaldeyde gels. I dont think that is due to a better resolution 
of the first method, but I rather think that is an artifact.
Do you have any suggestions.

Thanks Saverio
