Figure 6. — Biotin-labeled IL-13.E13K-D2-NLS localizes to the nuclei of G48a GBM cells. (A) Cellular localization experiments carried out in another high IL-13Rα2 expressor, G48a cells. Wells having no labeled proteins were used as controls. (B) Z-stack analysis of G48a cells treated with IL-13.E13K-D2-NLS at 24 hours. (C) Cellular localization experiments for the IL-13.E13K-D2-NLS, IL-13.E13K-D2, IL-13.E13K-NLS, and the IL-13.E13K were carried out in G48a cells concomitantly and their trafficking documented using confocal microscope. Cells with no labeled proteins were used as controls. The data are representative of 2 independent experiments.
