Electron microscope autoradiograph showing radiographic leucine over elements of the rough endoplasmic reticulum. A few grains are also found over small, smooth surfaced vesicles of the Golgi complex...

Early transmission electron micrograph of a thin section of a secretory cell from guinea pig pancreas illustrating vesicle trafficking between the rough endoplasmic reticulum and Golgi apparatus (uppe...

Transmission electron micrograph of smooth microsomes obtained by fraction of guinea pig pancreas. Cell fractionation confirmed that newly synthesized acinar cell secretory proteins moved from the rou...

Early transmission electron micrograph of secretory cell from the guinea pig pancreas. Secretory granules are prominent in the lumen of the rough endoplasmic reticulum. Image made available by James ...

Early transmission electron micrograph of a thin section of a secretory cell from guinea pig pancreas showing endoplasmic reticulum at left and Golgi apparatus at right. Image made available by James...

Transmission electron micrograph of rough microsomes obtained by fraction of guinea pig pancreas. Cell fractionation confirmed that newly synthesized acinar cell secretory proteins moved from the roug...

Electron microscope autoradiograph showing radioactivity associated with zymogen granules in the guinea pig pancreas 4 hrs after injection. Image corresponds to Figure 9 in J Cell Biol. 1964 Mar;20:4...

Electron microscope autoradiograph showing the high concentration of radioactivity over the condensing vacuoles of the Golgi complex twenty minutes after injection. Image corresponds to Figure 7 in ...

Electron microscope autoradiograph taken 20 min after injection showing that the radiographic label has migrated from the rough endoplasmic reticulum to the Golgi complex. Most of the radioactive gra...
