Immunocytochemical labeling of phosphorylated δ1-Catenin in A431 control (top) or treated with pervanadate (bottom). The fixed cells were labeled with mouse monoclonal antibodies to δ1-Catenin (a.a. 275-285), δ1-Catenin (Tyr-228), δ1-Catenin (Tyr-280), and δ1-Catenin (Tyr-302). The antibodies were detected using Goat anti-Mouse secondary antibodies conjugated to DyLight® 594.
