Our lab has been using the Genius kit from Boehringer Mannheim with
terrific results. I've used it to screen lambda ZAP II expression
libraries, Southerns and Northerns. Most of the time, colorimetric
detection is plenty sensitive. For some screenings, chemiluminescence is
recommended. One of the greatest features of non-radioactive probes is the
ability to reuse them. Simply pour the hybridization fluid into a conical
tube and freeze. I've reused such probes seven times with little
discernable loss of signal!
