TEM of nontransformed and HBsAg-expressing potato cells. (A) Thin-section TEM image of a nontransformed FL1607 potato cell. (Bar = 315 nm.) (B) Thin-section TEM image of a transgenic HB114–16 transgenic potato cell. Arrows indicate membrane-bound vesicles containing 17-nm putative HBsAg particles. (Bar = 200 nm.) (C) Enlarged image of membrane-bound vesicles containing 17 nm putative HBsAg particulate structures indicated by arrows. (Bar = 96 nm.) Cp, chloroplast; E.R., endoplasmic reticulum; Mito., mitochondrion; Vac., vacuole.
