Figure 2. Retransformation assay and test against other bait constructs. The 2P152 and 2P141 prey constructs were re-co-transformed
into yeast with the original PITX2 bait construct and the interaction phenotypes were re-assessed. The results of the X-gal
assay are shown here. Blue colonies indicate positive interaction while white colonies indicate no interaction. The 2P152
and 2P141 prey constructs were also tested for interactions with the PITX2 homeodomain bait construct, and a full length FOXC1
bait construct, both yielding negative results. The 2P152 and 2P141 prey constructs were also co-transformed with an empty
bait construct to test for prey self-activation.
