Does it have to be a Northern? Could you get away with either cloning
out the relevant cDNAs and/or just doing RNase protection assays? I'm
thinking that the RNAs you're looking at are relatively rare, and RNase
protection is supposed to be severalfold more senstive than a Northern.
Of course, it won't give you size info, but if all you want to show is
that it is indeed differentially expressed, maybe this will let you
finish. I've had good luck with the RPAII kit (and MEGAscript) from
Ambion (the usual disclaimers in this case). Good luck!
