I'm not sure of any reason why it wouldnt work other than the fact people
always say to do the RT step w/ dT or p(dN)6. I assume you checked that the
3' PCR primer is _antisense_ with respect to the mRNA template? I don't know
how Clontech have their primers set up, but off the top of my head it seems
more logical for the 5' PCR primer to be the antisense one wrt the mRNA.
Just an idea.
