FIG 3.
Immunoprecipitation of TREX-293 GRA15II and RH-GRA15II. TREX-293 GRA15II and ROP38I were induced with tetracycline (1 μg/ml), harvested 16 h postinduction (A, B), or infected for 8 h with RH parasites expressing HA-tagged GRA15 (C). The cells were lysed for HA immunoprecipitation with magnetic beads. Immunoblotting was performed on 10% input and 30 μl of the HA magnetic beads with (A) HA antibody, (B) TRAF2, TRAF3, and TRAF6 antibodies, or (C) HA, TRAF2, and TRAF6 antibodies and lamin A as a loading control of the 10% input.
