there are no silly questions. Not asking them is silly. Did you ever
notice that you lost knowledge when you were asking something?
Antisense mRNA probably will be degraded as soon as you add it to the
TC flask. You may transcribe it in to cDNA, clone it into a plasmid
and transfect this plasmid.
If you should want to use antisense oligos, synthesize full
phosphorothioates. They are expensive (longer synthesis time), but
very stable. So you'll be lucky if you know someone owning a
When you design the probes, I'd suggest to make some
target mRNA structure calculations (Ralf Zucker's RNAFOLD is an
internet tool for this) and place them in the loops, not in the
stems (except you should want to stabilize your target).
There is an IMHO intersting journal on this topic, Antisense Research
