Fig. 5. BicC, Orb and Bru interact in vitro. (A) Immunoprecipitation experiments
were performed on total ovarian extract using
-Orb (lane 1),
-BicC (lane 2) or
-Hrp48 (lane 3) antibodies, or beads alone
(lane 4). After precipitation, proteins were detected using
-Orb
antibodies. Equal amounts of extract were used in each sample. No Orb protein
is retained on the beads alone (lane 4) or with
-Hrp48 (lane 3)
antibody. Orb is readily precipitated by
-Orb (lane 1) and
-BicC
(lane 2) antibodies. (B) Bru protein is pulled down from total ovarian extract
by the
-Orb antibody. The same blot was probed with
-Orb (1) and
-Bru antibodies (2).
