Figure 3

Ultrathin cryosections of PC12 cells showing the localization of rbet1. (A) Double immunogold labeling for rsec22b (10 nm gold) and rbet1 (15 nm gold). Both SNARE proteins localize to the same VTC membranes. Label in the Golgi (G) is restricted to the cis-most cisterna (arrow). (B) Double immunogold labeling for rbet1 (10 nm gold) and COPII (15 nm gold) showing colocalization on VTC membranes. (C) Double immunogold labeling of rbet1 (10 nm gold) and COPI (15 nm gold). The arrowhead points to a tubular VTC membrane that contains rbet1, and is coated with COPI. Bars, 200 nm.
