We do dig-labelled gel shifts, and we prefer to transfer the gel
to a positively charged membrane, and then do detections. We
simply transfer the gel by capillarity, and get most of the DNA
transferred in 1-2 hours (you can also transfer overnight, as
well).The DNA stays stuck to the membranes pretty well, and UV
crosslinking is not necessary, though it does improve the signal.
In our experience, any positively charged membrane is okay - we
are currently using NEN genescreen plus.
