: I had the same problem, using the Perkin-Elmer GeneAmp kit.
: I ended up switching to random hexamers for the RT step.
: Perkin-Elmer techies have suggested that anchoring the dT tail with the
: last base of the gene might help.

: They also suggested that I make sure that I do the initial 10 minute
: incubation at 20 to 25 C, and that I increase the RT time from 15 min to
: 60 min.

: If you are using the Perkin-Elmer kit and have no particular reason to
: use the dT primer, I would suggest switching to random hexamers.
