When you say duplicates, do you mean using fresh batches of RNA?  Only
bands which are reproducibly differentially expressed, ie, those showing
differential expression in seperate lots of RNA, can be expected to show
differential expression on a Northern. Even then, it's still not
guaranteed. According to most of the literature, bands should be larger
than 200 bp.

  I'd be interested in receiving a summary via e-mail of responses you
receive to your original question-
