(a) GST-interaction assays were performed with the internal deletion mutants of GST-WT1 (schematic) with full length His-MAD2 and immunoblotted with anti-MAD2 and anti-GST antibodies. (b) Co-immunoprecipitation assays were carried out with whole cell extracts derived from HeLa cells that had been transfected with either GFP vector, GFP WT1 (?/?) or GFP-WT1 (?/?Δ4) using anti-MAD2 or anti-WT1 antibodies. (c) Co-immunofluorescence analysis was carried out in WiT49 cells with anti-MAD2 and anti-WT1 antibodies at the pro-metaphase stage of mitosis. DNA was stained with Hoechst. The scale bar is 10 microns. (d) M15, WiT49 and K562 cells were treated with 60 ng/ml nocodazole for 24 hours, whole cell extracts prepared and immunoprecipitation performed with anti-MAD2 antibodies followed by immunoblotting with WT1 antibody. Input is 10% of the total whole cell extract.
