Figure 6. Confocal images of p27 and PKC_α colocaliztion in RPE cells. PKC_α and p27 have obvious cytoplasmic localizations and slight nuclear localization, and mostly colocalized in the cytoplasm of the cells stimulated with PMA, thymeleatoxin, and siRNA- PKC_α. PKC_α (FITC, green label) p27 (Cy3, red label), nuclei (Hotchest 33342, blue label), PKC_α, and p27 colocalization (yellow label).
