Well, thanks for your suggestion, Klaus. I may try using RNAse although I 
don't really believe in this explanation: if the unexpected band in the 
genomic PCR was due to RNA contamination I should also see a minor, misspliced 
band. I don't see why only the correctly spliced product would 
contaminate/amplify?

I will... provided I find one.
