Piwi and Armitage interact physically. (A) SDS–PAGE of a Piwi immuno-precipitation (IP) alongside a control IP from OSC lysate stained with silver. A molecular weight marker is shown to the left and Piwi and Armi bands are indicated. (B) Western blot showing co-IP of endogenous Armi with Piwi from OSCs and ovaries. Pre-immune serum was used for the control IP. (C) Western blot showing co-IP of endogenous Armi with GFP-tagged Armi from ovary lysate. (D) Western blot showing co-IP of endogenous Armi with Piwi in the presence or absence of RNAse.
