Electron micrographs of multimerin-transfected AtT 20 cells, double-labeled for multimerin (10-nm gold) and ACTH (15-nm gold). Some granules contained only multimerin (sg2), whereas others contained both ACTH and multimerin (sg1, and inset; original magnifications: main panel, ×60,000; inset, ×120,000).
