Oligo dT for RT?

[POPOVA]

Is there an optimal length for oligo dT to prime a reverse transcriptase
reaction?  We want to synthesize such a primer.  Any benefit in a range of
lengths? Any reference?  Thanks

DEAR ELWYN,
I USE OLIGO dT 12-18 MER FROM PHARMACIA AT 40 C WITH
SUPERSCRIPT RT (BRL).  MAYBE 18-20 MER WOULD BE EVEN
BETTER FOR THIS TEMP. RT-PCR PRODUCTS CORRESPOND TO
cDNA ABOUT 200O BP.
