Hi gberna ,
I  _guess_  from your post that you are working with DNA Microarray's and 
that you are using the sort where DNA oligo's are spotted on poly-lysine 
coated slides. If that is true look here for more information :

I use a special designed random 9-mer Oligo which has a 5'-Cy5 label.I do 
one or two test hybridisations with this Oligo for each batch of printed 
Microarray's , just following our standard protocol.This will stain all the 
spotted DNA's equally , if the Microarray's are OK
