Dear Drosophila community:
I tried to make recombinant chromosomes with some Gal4 lines. In order to
identify the recombinant lines which have the Gal4 elements, I did PCR with
primers in the Gal4 coding sequence. I had 3 Gal4 lines, and used two sets
of PCR primers. Both sets of PCR primers only work on 1 of the lines. All the
three lines can drive the UAS-lacZ expression. For one of the lines, I also
tried to do southern blot with part of GAl4 sequence, still I can not see any
signal. I am really confused by the results. Are there different kinds of
Gal4 clones? The primers that I designed are based on the yeast gal4 sequence
from the genebank.
Any information will be greatly appreciated.
