Comments concerning this interaction

Source was embryonic cytoplasmic extract of wild-type fly line; bait produced from endogenous gene; prey produced from endogenous gene.

(Gangaraju et al., 2011)

piwi protein was purified by sequential DEAE sepharose, BioRex-70, Heparin and Superdex 200 column chromatography to isolate associated factors.
