Western blot analysis of WT and DE3 (Δ-Ex3) β-catenin in tracheal, esophageal, and lung protein. Genotype is indicated above each lane. Blots probed with α–N-terminal (α–N-term) β-catenin show the epitope present in the WT β-catenin, but deleted in the DE3 from. Blots probed with α–C-terminal (α-C-term) β-catenin detect both the WT and DE3 forms. Actin was used as the loading control (C). Dual-color detection methods were used, but color-separated monochrome images are presented here.
