dsDNA cycle sequencing - HELP

[Paulo Magalhaes]

I'm trying to set up a "dsDNA cycle sequencing" protocol,
using a clean dsDNA PCR product as template, an unlabeled
oligo, a mixture of the 4 dNTPs, 35-SdATP and ddNTPs.
My A and C lanes show very faint bands, especially for
the longer fragments, which I presume is due to a bad
d:ddNTP ratio.
Can someone help me save many hours of trials?
I don't want to use 32-PdATP.
A detailed protocol is most welcome.
Thank you.

Paulo
