Hi!

If anyone could help me out it would be much appreciated!

I am looking for protocols that would allow me to do single-copy 
eukaryotic genomic Southerns, as I am looking for possible homologues 
to a human gene in other eukaryotic organisms (mouse, rat, 
chicken, Guinea pig, calf, ...). My problem lies in the fact that, using 
a 294 bp cDNA fragment which encodes the DNA-binding 
region (88 aa) of the much larger human protein (1093 aa), I have not
been able to get a signal when performing a Southern with my 
control (human epithelial cell genomic DNA).

Thanks for your time and attention!
