I used DIG/HRP to screen phage cDNA libraries and gridded BAC (colony)
libraries and was very pleased. I can't comment on aDIG-AP for this kind
of application because I switched to HRP/luminol for all my
hybridizations. I think I heard that AP detection can have problems if
you use nitrocellulose membranes. If anyone knows if this is true (and
why), let me know as I'm curious.
