Fig. 3. APC2 mutant proteins. (A-C) Protein samples derived from ovaries of APC2 allele/deficiency females, or from embryos whose mothers and fathers were APC2 allele/deficiency, so that only mutant protein was present (see Materials and methods), were immunoblotted with anti-APC2-CT (A,B) or anti-APC2-NT (C). Arrows indicate mutant proteins; arrowheads indicate background bands.
