  • a BD-AD, Positive results were obtained when the first polypeptide listed was fused to GAL4-AD and the second polypeptide listed was fused to GAL4-BD, and further that the positive signal was not observed when reciprocal fusions were tested. BD-AD; AD-BD, Positive signals were obtained regardless of which polypeptide was fused to either of the GAL4 segments.
