I don't have any good advice for this. I have never been able to get
riboprobes off of my Northern filters. Even pouring boiling 0.1% SDS on
them and letting them sit for 3 minutes doesn't get it all off.
My suggestion would to use DNA probes. A great way to get high activity
DNA probes is to PCR amplify up some probes with a radioactive nucleotide
in the mix! Should give you the sensitivity you're looking for (if you're
just using riboprobes for the heck of it, just use random priming).
