Figure 1. Representative immunostaining results for E-cadherin associated protein expression. A: The first antibody replaced with IgG was used as the negative control. B: The representative positive β-catenin immunostaining in conjunctival tissue was used as the positive control. C: E-cadherin protein expression detected in the membrane (400×). D: β-Catenin protein expression detected in the membrane (400×). In addition, aberrant localization of β-catenin was also detected in the cytoplasm/nuclei (E) and nucleus (F) (400×).
