I recently starting using Amersham ECL direct nucleic acid labeling 
and detection system. I'm screening phage genomic libraries. it seems 
to be working ok- but possible positives look faint, I'm not getting 
any really strong signal, I've altered the washes, but I still never 
seem to get a clean signal, I often get background, but then when I 
increase the stringency, I get nothing,  I know the kit should work, 
many people have suggested it- sounds like the alkaline phosphase 
gives a stronger signal than the HRperioxidase- any comments, thank 
you in advance.
