I fooled around with DIG detection a few yr ago, before the "beta testing"
results had been incorporated into the new protocols. Results: lotsa black
film. So I bagged it.

Couple of yr ago I decided to try non-R/A sequencing again, using a
biotinylated primer and detecting with the NEBL Phototope system. Worked
fine. Last yr I ported those same primers to cycle sequencing protocols--
Thermosequenase from Amersham and Sequitherm from 5'>3'--and the results
were just as acceptable. I sequence PCR products of human genomic DNA BTW.
It is very sensitive, and you can get away with a less-than-pristine template.

If you decide to try it let me know. I have a few tricks to ease the pain...

Good Luck,
