We did genomic Southerns in a molecular biology course this year. We
used an actin probe derived from Dictyostelium to detect homologoues in
D. melanogaster. Dicty actin-8 PCR was labelled with DIG-UTP by random
priming using the Genius kit. Using the color reactions (not the
chemilumiscent reaction), we were able to clearly detect 6 bands in a D.
melanogaster HindIII digest. I was surprised that this method worked
with a genome the size of Drosophila, but it did.
