Figure 1. Claudin-23 localizes to cell-cell junctions in X. laevis epithelium. A. Representative live confocal imaging of BFP-ZO-1 and eGFP-Claudin-23 in gastrula stage Xenopus laevis embryos. Images are max intensity projections of 34 z planes. B. Line scan across three junctions (n=1) is shown, indicating that the peak intensities for Claudin-23 and our TJ marker, ZO-1, overlap.
