An electron micrograph of a thin longitudinal section of the Yellow mutant of the unicellular green alga Chlamydomonas. Unlike cells grown in the light, the chloroplast appears fragmented and lacks t...

Zymogen granule fraction Calf. This study demonstrated directly that the enzyme and proenzyme composition of proteins in pancreatic juice collected from an indwelling catheter in the bovine pancreati...

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.

Transmission electron micrograph showing normal glomerulus basement membrane filtration slits 15 min post IV ferritin administration. At this time point frerritin is in the capillary lumen basement m...

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...

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

Transmission electron micrograph of mitochondria and mitochondrial granules from guinea pig pancreas. The use of osmium tetroxide as a fixative for electron microscopy was first described by Dr. Palad...

Transmission electron micrograph of a tangential section of a rat glomerulus basement membrane. The series of images in this group have particular historic and cell biologic importance for determini...

Transmission electron micrograph of rat kidney filtration barrier. Micrograph illustrates the basement membrane between fenestrated capillary endothelium and podocyte foot processes at intermediate m...

Transmission electron micrograph of a rat kidney filtration barrier. This tangential section illustrates the fenestrated endothelium and basement membrane. The series of images in this group have p...
