Transmission electron micrograph of a thin section of plastic-embedded material from the 'rough microsome' fraction of a preparation of rat liver. Subsequent to this early image, 'microsomes' became ...

Transmission electron micrograph of a thin section of a preparation of isolated and plastic embedded rat liver polyribosomes (also known as polysomes). Polysomes associated with the endoplasmic reticu...

Transmission electron micrograph of a thin section of a fibroblast from the ventricular myocardium of a rat showing a transverse view of rough endoplasmic reticulum (RER, sometimes termed granular end...

Transmission electron micrograph of a thin section of a capillary from the ventricular myocardium of the rat showing part of a reticulocyte (immature erythrocyte) in the lumen of the capillary. The re...

Gallery of transmission electron micrographs of ribosomes purified from a rat liver homogenate by sucrose gradient centrifugation, and negatively stained with uranyl acetate. The 3 columns at left ill...

Primary rat hepatocytes in culture fixed and stained for beta-tubulin. The microtubules form a network throughout the cytoplasm. In this image they are seen originating from a brighter and denser re...

High magnification view of rough endoplasmic reticulum (RER) from rat pancreas showing RER and ribosomes, both bound (RiB) and free (RiF). Ribosomes were originally called Palade particles, as Palade ...

Nuclear pores are clearly seen in these transmission electron micrographs of cells after cryo-fixation, freeze-fracture and surface replication. Upper panel shows the outer surface of of the nuclear e...
