Hi there,
           Help !!! I am having real problems to get signals in genomic 
southern blot hybridization. The controls are working, but the signals in 
the genome are not coming up even with two or three days of 
hybridization. I am new on Drosophila, and owuld like to receive some 
adive about how much DNA to put in the slots, how much specifically 
labeled (cpms/ug) should be the probe for a single copy gene, and so 
on...please, anybody with experience in genomic hybridization give me 
some clues, because I amd riving crazy in such basic step !!!
