Source was cell extract of S2 cell line; bait produced from endogenous gene; prey produced from endogenous gene.
Source was embryos of transgenic fly line; bait produced from tagged transgenic construct; prey produced from endogenous gene.
Embryo extracts were crosslinked, immunoprecipitated and the level of specific coimmunoprecipitated mRNAs was quantified by RT-qPCR.
Positive control.
