Figure S1. Overexposure of the staining of untransfected N2A cells with αe2 and Abcam2828 (negative controls of Figure 2) reveals that faint staining patterns do not overlap with heterochromatin.

For αe2, the signals are mostly cytoplasmic, and for Abcam2828, they are intra-nuclear, but overlap with regions that are less intensely stained with DAPI, and thus more likely correspond to nucleoli than to heterochromatin.
