Source was yeast cell line; bait produced from transgenic construct; prey produced as transgenic fusion protein (prey was previously cloned reagent).
Three-hybrid system: DNA binding component is lexA fused to MS2 RNA binding protein, bridging component is bait mRNA in tandem to MS2 binding sites, transcriptional activation component is prey protein fused to B42.
Source was adult ovaries; bait produced from tagged transgenic construct; prey produced from endogenous gene.
