  I would agree that RT-PCR is more sensitive and requires less RNA, but I'm not 
sure it's harder to quantitate. If you want a reasonably accurate quantitation I 
would recommend RT-PCR (or RNase Protection)....if all you need is a yes/no 
answer to whether it's expressed I would try Northerns first....but if your 
message isn't very abundant, you might need to use RT-PCR eventually anyway.
