Comments concerning this interaction

Source was fixed embryos of transgenic fly line; bait produced from tagged transgenic construct; prey produced from tagged transgenic construct.

(Boube et al., 2014)

Using this assay, the abd-A-MED19 interaction is observed only with an abd-A homeodomain construct, and not for full length abd-A.
