If you have probe for it, IMO Northern is probably your best bet. Then you 
can show a picture of the EtB-stained gel or the methylene blue stained 
blot to show you have equal loading and not even have to worry about a 
"control" gene, which you may not be able to find.

Is there a particular reason you are trying to avoid a northern?
