<p>FLAG-tagged RAGE and mutants were transfected to HeLa cells and intracellular immunocytochemistry was performed. Scale bars: 50 µM for all images. (<b>A</b>) Localization of RAGE (WT). Blue: DAPI (stain nucleus); green: anti-calnexin (as the ER marker); red: anti-FLAG. Co-localization is demonstrated by the yellow color of the merged image. (<b>B</b>) Co-localization of RAGE (C259S/C301S) with the ER marker calnexin. (<b>C</b>) Co-localization of RAGE (C259S) with calnexin. (<b>D</b>) Co-localization of RAGE (C301S) with calnexin.</p
