i think clontech sells antibodies against the GAL4 BD and AD domains so
you can test expression of your hybrid proteins.  I have also used
the yeast 2-hybrid system to pull out proteins that make a lot of sense
but they were all out of frame wrpt the vector sequence (pACT2).  My guess
is that somehow the plasmid sequences were mutated when i passed
transferred them into E. coli (i used DH5a) for amplification and
