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...

A transmission electron micrograph of a Leydig cell isolated from guinea pig testes.The eccentric nucleus and several pale lipid droplets are visible. Numerous mitochondria and smooth endoplasmic ret...

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...

Transmission electron micrograph of cell fractionation of guinea pig pancreas microsomes. Rough microsomes, the cell fractionation equivalent of the rough endoplasmic reticulum with bound ribosomes in...

Transmission electron micrograph of guinea pig pancreas mitochondria and lipid droplet. The use of osmium tetroxide as a fixative for electron microscopy was first described by Dr. Palade at the Rock...

Transmission electron micrograph of mitochondria from guinea pig pancreas. The use of osmium tetroxide as a fixative for electron microscopy was first described by Dr. Palade at the Rockefeller. Anot...

This image, produced by the freeze-fracture technique, shows regional specialization in the structure of mammalian sperm. The P-face of the plasma membrane of a guinea pig sperm tail can be divided i...

This electron micrograph shows the P-face of a small region of membrane from the midpiece of guinea pig sperm. The changing distribution of intramembranous particles (IMPs)in this image provided some...

Transmission electron micrograph of a cell fractionation of golgi bottom fraction. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of Medicine.

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...
