T-Antigen and β-catenin co-localization <i>in vitro</i>.

<p>Double labeling immunocytochemistry for β-catenin (Panel B, Fluorescein), and T-Antigen (Panel C, Rhodamine), performed in HTC116 colon cancer cells transiently transfected with T-Antigen show the co-localization of both proteins in the nuclei of the majority of cells (Panel E, arrows), while in non-transfected cells in which there is no expression of T-Antigen, β-catenin remains exclusively in the cytoplasm (Panel E, arrowheads).
