Two-hybrid system: yeast GAL4-BD/GAL4-AD
Source was yeast cell line; bait produced as transgenic fusion protein; prey produced as transgenic fusion protein (prey was previously cloned reagent).
Interaction in vitro; bait produced as a recombinant fusion protein in bacterial system; produced and labeled by in vitro translation.
Drosophila veli was immunoprecipitated with an antibody raised against the mammalian ortholog.
Source was embryos of transgenic fly line; bait produced from endogenous gene; prey produced from transgenic construct.
