Differential Display: best kit/primers?

[Paul A Bucciaglia]

Hello all,

I'm getting ready to try DDRT-PCR and would like to get comments on good 
or bad experiences with various kits.  It seems like the kits are a good 
deal based on the cost to synthesize the primers, although Operon had a 
set of primers-only that was considerably cheaper than complete kits.
I also recieved some info on kits from Clontech, Genomyx, and 
GenHunter--any comments on these? 

The Clontech kit used one primer (poly-T) for Rev. Txn.,  which cut down 
the number of reactions, while the other kits needed 4 separate Rev. txn 
reactions.  

Again, any feedback on these or other kits would be appreciated.

TIA,

Paul B.
