Concanavalin A is a nonspecific ER stain, which could stain the nuclear envelope, the rough ER, and the matrix of some multivesicular bodies.
Substantial amounts of rough ER cisternae and mitochondria were closely associated with plasma membrane in close proximity to the microvilli (Figures 6(a) and 6(d)).
In SKM cells, the canonical ER distribution is not clear: cells may contain two major rough ER subcompartments, one without exit sites, localized in correspondence to the I-band, and a second responsible for export activity toward the Golgi Complex (GC), near the Z-disc.
