Fig. 2. Co-localization of IRP1 with the ER marker calnexin in SW1088 cells. (A-C) Representative cells selected from D (arrow). A-C are confocal images of the same cells showing the intracellular distribution of IRP1 (green in A), the ER marker calnexin (red in B) and the merged image (C). The yellow indicates strong overlap in the perinuclear region.
