DDRT-PCR Northerns

[McMaster Lab]

Because DDRT-PCR is very sensitive, you may be isolating single copy 
mRNA.So,unless you have a screaming hot probe and enough RNA on the 
Northern to swim in, you will never see a band on the autorad.
This of course is no help to you. We tried reverse Northerns but never 
had much success. Try S1 nuclease protection kit by Ambion.
Good Luck.
